Understanding your choice of forged valve bodies options
When it comes to choosing the right forged valve body for your specific application, there are several factors to consider. Valve bodies are a critical component in controlling the flow of fluids or gases within a system, and selecting the appropriate one can greatly impact the performance and longevity of your equipment.
Understanding your choice of forged valve bodies options is crucial in selecting the best option that suits your needs. Consider factors such as material type, size and shape, manufacturing process, and cost when making your choice. Choose forged valve bodies for their exceptional strength, reduced risk of failure, cost-effectiveness, and customization options.
What is a forged valve body?
The valve body, sometimes also known as the casing, is the main boundary of valves. It is the main component of the valve assembly as it is the framework that holds all components together.
The valve body is the first pressure boundary of the valve, which resists the fluid pressure load from the connected pipeline. It receives inlet and outlet pipes through threaded, bolted, or welded joints.
The valve body end is designed to connect the valve to the pipeline or equipment nozzle through different types of end connections, such as butt or socket welding, threaded or flange connections.
Types of forged valve bodys
(1) According to the purpose, the valve body can be divided into:
- 1) Shutoff type, permanently located at the inlet or outlet of cold, heat, or mechanical equipment, including gate valve body, globe valve body, plug valve body, ball valve body, butterfly valve body, needle valve body, diaphragm valve body, etc. Its function is to block the flow of fluid medium in the pipeline.
- 2) Adjustment class, which can adjust the pipeline flow according to pre-instructions, including an automatic or manual adjustment.
- 3) Protection type, mainly used to limit the rated pressure in the pipeline, also known as the safety valve body, such as ADS system automatic pressure reducing valve body, which is automatically opened.
- 4) Special category refers to valve bodies manufactured according to the unique design requirements of pipelines, such as sewage valve bodies installed at the lowest point, exhaust valve bodies installed at the highest point or inflection point of the transmission pipeline, etc.
(2) According to the main parameters and different pressure usage ranges, the valve body can be divided into the vacuum valve body, low-pressure valve body, medium-pressure valve body, high-pressure valve body, ultra-high pressure valve body, and filter. According to different working temperatures, valve bodies can be divided into ultra-low temperature valve bodies, normal temperature valve bodies, medium-temperature valve bodies, and high-temperature valve bodies.
(3) According to the driving method, valve bodies can be divided into automatic valve bodies, power-driven valve bodies, and manual valve bodies.
(4) According to the valve body’s nominal size and size specifications, the valve body can be divided into a small diameter valve body, medium diameter valve body, large diameter valve body, and extra-large diameter valve body.
(5) According to the structural characteristics, the valve body can be divided into truncated gate shape, plug shape, gate shape, swing shape, butterfly shape, slide valve body shape, track type, spherical shape, etc., based on the movement trajectory of the closing part in the valve seat.
(6) According to the connection method, the valve body can be divided into threaded connection valve body, flange connection valve body, welding connection valve body, clamp connection valve body, clamp connection valve body, clamp connection valve body, and clamp connection valve body according to the connection method of the valve body in the pipeline.
(7) According to material classification, valve bodies can be divided into metal material valve bodies and non-metallic material valve bodies.
The proportion of main components of the valve body (such as valve body, valve cover, gate, packing box, packing gland, valve rod, etc.) using forging technology is increasing, especially for valve bodies used under special working conditions, which have increasingly strict quality requirements and complex materials. Therefore, it brings market opportunities and technical challenges to the forging industry.

Dimensions of Forged Valve Bodies
The dimensions of forged valve bodies can vary greatly depending on the application, valve type, and materials used. Some common dimensions are:
Diameter:
-
Small sizes: Ranging from 1/4 inch (6.35mm) to 2 inches (50.8mm);
-
Medium sizes: Ranging from 2 inches (50.8mm) to 12 inches (304.8mm);
-
Large sizes: Ranging from 12 inches (304.8mm) to 60 inches (1524mm) or even more.
Thickness:
-
Small sizes: Ranging from 1/8 inch (3.175mm) to 1/2 inch (12.7mm);
-
Medium sizes: Ranging from 1/2 inch (12.7mm) to 2 inches (50.8mm);
-
Large sizes: Ranging from 2 inches (50.8mm) to 10 inches (254mm) or even more.
It’s important to note that these dimensions are just general guidelines, and the actual dimensions of a specific forged valve body may differ. The manufacturer’s specifications should always be consulted to ensure proper sizing and compatibility with the intended application.
How to calculate the size of the valve body?
To calculate the size of the valve body, you need to know the parameters related to the operation of the circuit.
The pressure is an important factor that must be taken into account, on the one hand, to avoid under-sizing the valve body, which could lead to leakage or rupture problems in the valve body, and on the other hand, to avoid oversizing the valve body.
The operating temperature, i.e., the temperature of the circulating medium and the ambient temperature around the valve body, must be determined. It is important to know the temperature extremes the valve body must withstand to select a valve body that can operate under these conditions, especially the materials used to manufacture the body, shut-off system, and seals.
The operating pressure, i.e., the pressure at which the medium circulates through the valve.
The flow rate and velocity of the fluid. The flow rate and rated velocity are essential to help you select the right valve body, especially for regulating that flow. The flow coefficient (Kv) is a theoretical value specified by the manufacturer that allows you to calculate the nominal flow rate of the valve body. It can be expressed in liters per minute (l/min) or cubic meters per hour (m3/h). The valve body manufacturer provides charts to determine this factor based on the required flow rate and nominal diameter.
The circuit’s nominal diameter (DN) is where the valve body is located. This is essential to avoid oversizing the valve body, which may lead to dangerous plant operation or avoiding under-sizing, which may lead to a significant pressure drop and rapid valve body damage.
The Forging Process of forged valve bodies
The forging production process for valve forgings may seem simple, but it is complex and ever-changing. The application of valve products is spread across various industries, and many new materials and processes require time to practice and research repeatedly. Some new knowledge points need to be learned and explored.
Typical product forging process introduction (body, cover)
Flange valve body overall forging
Flange and valve body forging as a whole have been the development direction in recent years; the advantage of this is to completely avoid welding defects and enhance the reliability of the valve; the disadvantage is that the forging difficulty increases, material utilization rate decreases, this form of structure will gradually be promoted to replace the welding structure, how to further optimize the forging process is the responsibility and obligation of forging colleagues.
(1) Forging process is as follows: raw material inspection → feeding → heating → flattening → pre-forging → final forging → edge cutting → heat treatment → surface cleaning → non-destructive inspection → rustproof → packaging → delivery.
(2) Basic information on forging parts. External dimensions of forging blank for double flange valve body: maximum diameter at flange 125mm, the total length of the valve body 164mm, as shown in Figure 1.
Figure.1 Double flange valve body forging blank
1) Blank making. The raw material used 110mm diameter, 140mm length of F316 stainless steel round bar material. The round bar stock is flattened to 70mm directly on the die plane, as shown in Figure 2.
2) Pre-forging. Pre-forging shape flange diameter of 125.86mm at both ends, flange cross-sectional area of 12435mm2, and the length between the two ends of the flange is 165mm. Billet, the material is 70mm high, 140mm wide, 160mm long, and has a cross-sectional area of about 9800 mm2. Billet shape and pre-forging shape comparison: the cross-sectional area is smaller than pre-forging; the length is smaller than pre-forging. The flattened material is placed directly in the pre-forged cavity (Figure 3). The material was not upsetting the middle flange part separately during the billet-making process.
Figure.2 Blank Making
3) Final forging. The pre-forged billet is put into the final forging die and directly final forged (Fig. 4).
Fig.3 Pre-forging
Figure.4 Final forging
4) Edge cutting. After the final forging, the blank is put into the cutting-edge die, the flying edge is removed, and the forging is opened into the final shape (Fig. 5).
Supercritical valve forging
Mainly used in thermal power projects, small forgings are not distinguished from the conventional forging processes, basically the same, so they will not be introduced. For large forgings, weighing several tons, our forging process is as follows:
(1) must ensure the correctness of the heating process and adequate and appropriate forging ratio because we re-heat, the grain will recrystallize and grow through the forging process of external forces on the grain refinement, the forging process of heating temperature, holding time, the heating rate must be strictly controlled to avoid internal cracking; the cooling process is also particularly critical, alloy steel needs slow cooling, can take pit cooling, cooling with the furnace The cooling process is also particularly critical, the alloy steel needs slow cooling, can take pit cooling, cooling with the furnace, control cooling, etc., with the conditions of the enterprise, it is recommended that the forging directly after the furnace through a given program to control the cooling rate.
(2) 10-inch valve body forging process route. Material entry inspection → material → heating → pre-forging billet → mold forming → out of the mold.
(3) the basic information of the valve body. 10-inch valve body forming forgings, the total mass of forgings is 1270kg, die assembly diagram and forming parts as shown in Figure 6.

CAP1400 blast valve forging
This is the project of “Liaoning Science and Technology Innovation Major Special Project” undertaken by our company; forging is an important part. Currently, CAP1400 is a worldwide innovative product, AP1000 is a foreign advanced technology introduced by China, and the successful independent research and development of CAP1400 is a milestone product that will be used in Hualong-1.
Blast valve forging process route for material admission inspection → under the material → heating → pre-forging billet → tire die buckling type → punching shaping. Blast valve forging and forging process simulation are shown in Figure 7.
Figure.7 Blast valve forging and forging process simulation
Ball valve body casting to forging
From the perspective of product performance, forging is superior to casting, but the process requires us to continue to improve to make up for the lack of material utilization. Figure 8 ball valve body forging is the casting parts with forgings to replace, is a future direction, need to forge colleagues to improve technology to create their own market areas.
LNG valve body and cover forging
LNG valve class forgings, mainly stainless-steel forgings, to prevent the subsequent process product quality defects, we try using a composite die. In practice, the scrap rate has been effectively curbed to produce good results, and the level of conventional product quality is basically the same. The composite die-cutting and punching design reduce the production of workstations to solve the problem of forgings punching and cutting-edge deformation needing to be bigger. The sketch of the composite die is shown in Figure 9.
Figure.8 Ball valve body forgings
Forging of nuclear-grade valve forgings
Nuclear-grade valve forging requires companies to obtain the appropriate qualifications; practitioners must be filed, operating procedures approved and filed in advance, and the whole process with traceability. Material suppliers to be in the range of qualified suppliers; inspection tests may not cross the point (E, R, H point). NDT personnel must be filed with the Nuclear Safety Authority and must not exceed the scope of testing. The acquisition of specimens and technical documents must be strictly consistent, etc. The forgings are shown in Figure 10.

Forging equipment selection and its advantages and disadvantages comparison
Hot die-forging mechanical presses
For valve forgings, and mass production, we usually consider the equipment is hot-die forging mechanical press; the production process is easy to control, has high efficiency, excellent dimensional accuracy, and moderate manufacturing costs. We can select the equipment that should be used according to the theoretical formula calculation or practical experience, which is the basic theoretical knowledge that ordinary technicians can master. The production environment is clean and environmentally friendly, the labor conditions are good, and it is easy to realize automatic production.
Electric screw presses
Compared with friction presses, they have greater product advantages and are being popularized and used at home and abroad, and have a tendency to replace hot-die forging mechanical presses; after all, the one-time investment cost is lower, and the product quality and production efficiency are more satisfactory, and they can also be controlled automatically. The forging process is produced using robotic operations.
Die forging hammer
Simple valve forgings can choose to use such equipment because there is no ejector device, the product is out of the die angle, size needs to be better controlled, cavity arrangement is difficult, and precision forgings are difficult to ensure the accuracy of more restrictions.
Multi-directional forging presses
A multi-directional die forging press should be the most appropriate choice of equipment for valve body products and tee products; the highest material utilization rate and precious metals would be more appropriate; improving production efficiency still needs further exploration. After improving efficiency, it has a wide range of market prospects. In the future, valve body forging attainment should be great in the tee field.
Tire die forging
This process can be selected appropriately for small batches, simple shapes, and large single-weight valve body forgings. The die is simple; the investment is not big; it can save material than free forging; the process is not complicated; forging is bigger, and can save raw material and machining costs; the metal flow line is also closer to the product shape, the performance is the more reliable, higher life. The product performance test bar can be taken from the product master, and the production efficiency is much higher than that of free forging.
Friction presses
If the batch is not very large, it is recommended to choose this type of equipment. Because from the equipment comparison, the efficiency is lower than that of hot-die forging press, but the equipment investment is lower, and the biggest advantage is that it can produce products with larger stroke requirements, with upper and lower ejector devices.
Hydraulic presses
The hydraulic press is a universal machine. The disadvantage is also prominent: the efficiency is the lowest. The advantage is that problems that cannot be solved by other equipment can be achieved with it.
For hammering
The use of less and less, it is not recommended to choose this type of equipment for the production of valve-type forgings.
How to check the quality of the valve body?
At present, in industrial production, the quality inspection of valves still has many problems, resulting in the completion of the project stage there are still a lot of valve leakage situation exists. Therefore, the continuous improvement of valve quality inspection is the main method to deal with the current quality of the existing valves effectively; we also need to test the problem of rational analysis and put forward effective recommendations.
The method of quality inspection of valves
Appearance inspection method
In the appearance of the valve inspection, first of all, to determine the problem of defects, which contains the specific location of defects, size, and type, etc., to check the appearance of the valve is flat and smooth—casting class valves without sand holes and obvious defects and forging class valves to verify the nominal pressure or pounds. In addition, to determine whether the defect will directly affect the function of the entire part, for the existence of serious defects in the valve need to do scrap processing. Second, the need to increase the training of inspection personnel, timely learning of inspection-related knowledge, and understanding of the impact of defects on the valve, with sufficient professional and technical knowledge.
Performance inspection methods
The valve performance inspection can be used to perform the sampling method. Check the material of the valve and the material composition; this is very important; the material that is not up to standard in the device will be used in a big problem. For the inspection of the valve, the material is mainly applied to the spectrometer; the first is to carry out the detection of the valve stem, then the nut, valve body, and other parts of the random inspection, and finally, the gate, to ensure that all structural parts are not jerry-built and can be used normally, the relevant quality inspection results are in line with the standards. At the same time, according to the need to check other items, after the valve is opened, the gate and seat are separated; it is necessary to ensure that the ball and the axis are parallel to the performance of the random inspection. In addition, it is also necessary to fully analyze the technical aspects, from the macro aspects of the development of defects, to summarize the law, as a basis for control, from the source to grasp the quality. The last thing is to check whether the switch is sensitive and whether the label is clear.
Pressure test method
The pressure test of the valve mainly includes the shell, low-pressure sealing, and high-pressure sealing tests. Before the shell test, the valve shall not be painted or coated with other coatings that can cover the surface defects. Pressurized to the installed valve body cavity, the ends of the valve closed, and the opening and closing parts partially open. During the experiment, it is necessary to observe whether there is valve leakage and then accurately record the data. During the low-pressure sealing test, the sealing surface should be clean and free of oil stains. The two-way seal valve should be successively pressurized at each end of the closed valve and the other – end open to the atmosphere to check the sealing surface leakage at the outlet end. The valve should be pressurized at the inlet end for a one-way seal marked with the media flow direction mark. The check valve should be pressurized at the outlet end. The high-pressure seal test and low-pressure seal test methods are the same. When the test medium is liquid, the leakage detection should be liquid droplets.
Quality inspection of the valve problem analysis
Structure and geometry quality problems
In valve manufacturing, many manufacturers, to reduce material costs, the choice of the thin wall thickness of the blank production, which will lead to insufficient valve wall thickness. The insufficient wall thickness of the valve cannot be applied to the high pressure, high corrosion of the oil and gas field production environment; not only the use of quality is not up to par, but there will be numerous safety hazards, the service life of the valve will also be greatly reduced, the economic benefits are not high. Valve structure design has the relevant specifications; if the valve manufacturing process is not implemented by the design structure will greatly reduce the quality of the valve. For example, if the needle valve cover and valve body connection thread stroke are too short, the thread preload is insufficient, and the cover will fall off during the high-pressure water test.
Appearance quality problems
Trachoma is a common defect on the surface of the casting valve, mainly appearing on the outer surface of the valve; trachoma has sand or white slag inside, irregular shape, and varying depth. Pores generally appear in the casting valve internal, surface, or near the surface; the surface is relatively smooth, round, or oval, sometimes isolated, sometimes clustered, and often coexisting with slag or shrinkage. Valve surface pores, or trachoma, will reduce its effective bearing area, easily cause stress concentration and reduce the impact resistance of the casting, fatigue resistance, and denseness. In addition, cracks, mechanical damage, heavy skin, scars, rust, missing parts, nameplates and paint off, and other phenomena are common valve appearance quality problems, and the need to avoid such problems as far as possible.
Pressure test quality problems
Many valve inspectors need help understanding the importance of the pressure test, resulting in the importance of the problem not being high and easy to cause leakage in the process. Some inspectors need clarification with the upper seal and packing structure; the upper seal test is not to test the packing structure, but to test the valve in the fully open state, the upper seal seat, and the stem to form a conical, spherical hard seal.
Valve material quality issues
The choice of valve materials needs to be more careful because different materials’ physical and chemical properties are different. And the difference in material properties will also affect the quality of the final use of the valve. In addition, the choice of materials should also be concerned about the economy while ensuring the valve’s performance. But now, many companies appear to save costs to the phenomenon of second best, which will reduce valve quality greatly; many safety hazards will endanger the lives and property of the relevant operators.
Strengthen the quality inspection recommendations
The appearance of the valve inspection recommendations
Different valves have different functional and reliability requirements; acceptable defects are not the same; the determination of the valve surface defects to be based on a comprehensive analysis of the use of the valve, the type of defect, location, size, etc., to scientific, fair and equitable quality inspection to meet the needs of oil and gas field engineering construction. And the appearance of the valve inspection must follow the relevant standards according to the actual situation of reasonable inspection. In addition, enhancing the professional quality of the inspector’s appearance is also a key factor in ensuring the quality of the valve appearance inspection, only to ensure the quality inspector achieves the best level of inspection.
Pressure test of the valve recommendations
The main purpose of conducting the valve pressure test is to test the leakage of the valve and the related quality. But the detection of valve leakage cannot simply rely on the relevant curve to judge but should find the source of leakage to clarify the specific location and cause of leakage. In addition, the data collection should also be accurate, according to the data collected on the characteristics of the valve for rational analysis and judgment, clear valve leakage and failure-prone to the location, timely feedback to the relevant manufacturing units, to modify the problem and strengthen the quality.
Suggestions on performance sampling
In the valve performance sampling, you can make quarterly sampling of different parts of the valve to reduce the occurrence of jerry-building events to a greater extent. In addition, the base number of samplings needs to be increased as much as possible to ensure the credibility of the sampling results. The sampling items should also be increased as much as possible to ensure that the quality of all aspects of valve manufacturing can be guaranteed. In addition, the performance sampling can also be carried out on a digital platform to improve the digital degree of performance sampling and to ensure the accuracy and credibility of the sampling.
As a control hub in pipeline systems, valve quality control is important for achieving safe, timely, and economical supply. Every valve manufacturer must recognize the quality of the valve. A rigorous and thorough problem analysis should be conducted for the problems during the valve quality inspection process to adopt targeted methods to ensure the quality of the valve, effectively prevent safety accidents, and improve the valve’s service life. There are many methods for valve quality inspection, and a reasonable selection and scientific analysis should be made during the inspection implementation process to ensure that the quality of valve use meets the standards to the greatest extent possible.
