Manufacturing Process of Stainless Steel Valves
Stainless steel valves are generally manufactured by two processes namely forging or casting. All valves are indispensable parts of any industrial system, but not all valves are created in the same way. For example, some valves are forged and other valves are cast. Forging and casting are two of the most common ways to create high-quality valves. The biggest difference between forging vs casting valve methods is how they’re carried out. For both forged and cast valves the process begins with molten metal being poured into a mould. Shrinkage is a defect commonly shared by castings and forgings.
Stainless Steel Forged valves are created using a forging method that involves shaping metals and alloys while they’re in their solid form. Heat and industrial-size tools deliver compressive forces to bend the metals and alloys, and dies are used to cut and shape the materials to create specific valves. Forging can be performed in most temperatures depending on the metals used.
- Companies don’t have to worry about wasted materials. Since forged valves are shaped into one solid piece, little effort is needed to rework the material to achieve the proper shape and size.
- Forged valves have a reputation for being strong, which make them ideal for handling high-pressure and high-temperature systems.
- Increase in impact and overall strength.
- Forging can create valves with less wall thickness.
- Forged valves can be heated and cooled more quickly, which allows them to adequately handle the stresses of systems that continuously cycle through start-up and phase-down processes.
- Forging boosts its resistance to common issues such as cracks, shrinkage, and porosity.
Unlike forging, Casting uses the liquid form of metal to create stainless steel valves. These metals are melted into a molten liquid and poured into various molds. Once the liquid cools and solidifies, it’s broken out of or ejected from the mold.
- It can create valves with complex shapes, patterns, and sizes with more intricate parts.
- Great cost-effective solution for many companies. It allows you to make valves using more types of metals and alloys.
- Casting valves provides an easier and less time-consuming way to make replacement parts when a system’s current valves break down and deteriorate.
- It doesn’t require as much labor as forging valves, casting helps to reduce machining costs, especially when creating valves of complex shapes.

Types of Stainless Steel Valves
Each type of valve serves a very distinct purpose. Such stainless steel valves are used in a number of industries around the world, including water management, chemical processing, and food production. Stainless Steel Valves are quite diverse and may be classified into a number of basic types.
Stainless steel valves can also be classified based on their functions:-
- Function
- End connection
- How it operates
- Types of Actuator it used.
Classification of stainless steel valves based on end connections:-
- Wafer and Lug end construction
- Screwed or threaded
- Flanged type ends
Classification of stainless steel valves based on actuator:-
The last way to classify the valve is, types of the actuator used to transfer the motion to operate the valve. The valve can be operated manually with the help of handwheel, lever, chain or by a gear wheel. An external power source such as an electric motor, air, hydraulic fluid or solenoid is used to operate valve from the control room. Check valve works automatically when subjected to the backflow.
- Hydraulic
- Pneumatic
- Manual
- Solenoid valve
- Motor
Classification of stainless steel valves based on mechanical motion:-
- Linear Motion Stainless Steel Valves
- Rotary Motion Stainless Steel Valves
- Quarter Turn Stainless Steel Valves
Types Of Stainless Steel Valves:
- Stainless Steel Check Valve:- Check valves are commonly used for the prevention of back flow into a pipeline.
- Stainless Steel Plug Valve:- A plug shaped valve that uses a tapered or cylindrical plug to stop or start the flow. Plug valve is Quarter-turn rotary motion Valve. Plug valve can be used in vacuum to high-pressure & temperature applications
- Stainless Steel Pressure Relief Valve:- Pressure Relief Valve also known as Pressure Safety Valve are used to protect equipment or piping system during an over pressure event or in the event of vacuum. This valve releases the pressure or vacuum at pre-defined set pressure.
- Stainless Steel Gate Valve:- A stainless steel gate valve functions as an on/off valve. The gate or disc located inside the value is raised and then lowered while a handle is turned. Such valves are not ideally suited for regulating flow, and using them in that manner could result in damage to the disc mechanism. Two styles of gate valves are available: rising stem and non-rising stem. Gate valves are used in almost all fluid services such as air, fuel gas, feed water, steam, lube oil, hydrocarbon, and all most any services.
- Stainless Steel Knife Valve:- Knife valves are actually similar in nature to gate valves. The main difference is that a knife valve is more compact than a gate valve.
- Stainless Steel Butterfly Valve:- Butterfly valve is a quarter-turn rotary motion valve, used to stop, regulate, and start the flow.
- Stainless Steel Ball Valve:- Ball valves are typically used as a type of on/off control without incurring a drop in pressure. These types of valves are ideally suited for situations requiring a quick shut-off. A 90-degree turn can complete a shut-off with this valve, as opposed to the multiple turns that would typically be necessary for manual valves.
- Stainless Steel Disc Check Valve:- Disc check valves, also called as non-return valves allow the flow to pass through them in only one direction and stop the flow in reverse direction. Because of this unique directional property, disc check valves are essentially used for some critical applications in the steam systems. There are 4 major types:-
- Diaphragm Valve:- In situations in which flow needs to be controlled with the movement of a diaphragm, a diaphragm valve is commonly used.
- Lift Check Valve:- Lift check valves work simply on the principle of gravity.
- Swing Check Valve:- In this kind of check valve, the disc or the closing element swings around a point to which it is hinged.
- Spring loaded Check Valve:- In this kind of check valves, tight shut-off it provided using a spring.
- Stainless Steel Globe Valve:- Globe valve is used to stop, start, and regulate the fluid flow. Globe Valves are used in the systems where flow control is required and leak tightness is also necessary. Globe valve provides better shut off as compared to gate valve and it is costlier than gate valve.
- Stainless Steel Needle Valve:- Needle valves are similar to a globe valve in design with the biggest difference that is the sharp-pointed conical disc and matching seat. Needle valves are designed to give very accurate control of flow in small diameter piping systems.
- Stainless Steel Pinch Valve:- Pinch valves consist of a plastic tube/sleeve which is made up of reinforced elastomers. The sealing/ closing action is achieved by throttling or pinching this sleeve/tube. Pinch valves are best suited for handling slurries and fluids having suspended solids. Pinch valves offer many benefits over the other types of valves. They can be used for handling corrosive fluids as there is no contact between the fluid carried and the actual valve mechanism. Generally, pinch valves are suitable for low pressure applications. When used with abrasive slurries, they should be used as on-off valves; if used for throttling purposes, the sleeve will get worn out.
Components of Stainless Steel Valves
The main parts of the most usual type of valve are the body and the bonnet. These two parts form the casing that holds the fluid going through the valve.

Functions of Stainless Steel Valves
- Stopping and starting a fluid flow
- Relieve pressure or create vacuum in the piping system
- Regulating a flow or pressure within the piping system
- Throttling the fluid flow
- Controlling the direction of a fluid flow
Advantages of Stainless Steel Valves
- While plastic valves are also not prone to rust or corrosion, they do not have the strength, durability, or resistance to high pressure that stainless steel valves have. Stainless steel valves are designed with a hydraulic system that prevents all leaks.
- Robustness
- Corrosion-Free
- Resistance Against High-Pressure
- Variety of Designs
- Leakage Proof
Disadvantages of Stainless Steel Valves
Stainless Steel Gate Valve:
• Gate valves cannot be opened & closed quickly
• They cause vibrations
• In systems where high-temperature changes irregularly, due to the load in pipe at the valve end, leakages in gate valves occur.
• The operation, maintenance, and repair of gate valves seating surfaces are complex.
Stainless Steel Globe Valve:
• Pressure loss is higher
• To close under high pressure, globe valves require a larger amount of force or an actuator with a large torque.
Stainless Steel Ball Valve:
• Ball valves are not suitable for permanent throttling.
• In residual fluids, the particles in the fluid collide with the surfaces and stick to them. This may cause leakage, abrasion, and other problems.
Stainless Steel Butterfly Valve:
• Butterfly valves have no tight shut offs
• Some portion of the disc is always presented to the flow, even when fully opened. This may result in a pressure switch across the valve, regardless of the setting.
Stainless Steel Check Valve:
• They cannot be used with pulsating systems
• Closing element may crash causing damage and excessive wear
Selection Criteria of Materials for Valves
Material | Material Code |
Austenitic Stainless Steel | CN7M, CN3MN |
Precipitation Hardening Stainless Steel | 17-4PH, 15-5PH |
Duplex Stainless Steel | CD4MCu, CD3MN, CE3MN, Alloy2205, Ferralium255, SAF2507, ASTM A890 |
Monel | Monel400 |
Hastelloy | Hastelloy C276, Hastelloy B2, CW2M, CW12MW |
Inconel | Inconel 600 |
Selection Criteria for Valves
1. Fabrication:- Will the component be machined, forged, cold formed or welded? The fabrication required should be considered from three perspectives: (a) How easy or difficult will it be to fabricate the component? (b) How will fabrication affect the alloy’s performance? (c) Will the quality of the alloy permit satisfactory fabrication?
2. Physical Properties:- These could include density or magnetic properties.
3. Corrosion Resistance:- Be sure to consider the environment and type of corrosion resistance to be encountered. The most cost effective stainless steel will have enough corrosion resistance to provide the required service life without the needless expense of over-alloying.
4. Mechanical Properties:- Strength is usually the most important mechanical property in the selection of a stainless steel. However, the designer may be concerned also with the alloy’s hardness, ductility, impact resistance, fatigue strength or stress rupture resistance – or, perhaps more than one of these properties. Furthermore, the potential effect of the desired mechanical property on the alloy’s corrosion resistance may be important.
5. Final Component Cost:- Do a thorough value analysis that includes the initial alloy price, the installed cost, and the effective life expectancy of the finished product.
Applications of Stainless Steel Valves
Valves have many uses, including controlling water for irrigation, industrial uses for controlling processes, residential uses such as on/off and pressure control to dish and clothes washers and taps in the home. Even aerosols have a tiny valve built in. Valves are also used in the military and transport sectors. In HVAC ductwork and other near-atmospheric air flows, valves are instead called dampers. In compressed air systems, however, valves are used with the most common type being ball valves. Valves are found in virtually every industrial process, including water and sewage processing, mining, power generation, processing of oil, gas and petroleum, food manufacturing, chemical and plastic manufacturing and many other fields.
Valves may be operated manually, either by a handle, lever, pedal or wheel. Valves may also be automatic, driven by changes in pressure, temperature, or flow. These changes may act upon a diaphragm or a piston which in turn activates the valve, examples of this type of valve found commonly are safety valves fitted to hot water systems or boilers. More complex control systems using valves requiring automatic control based on an external input (i.e., regulating flow through a pipe to a changing set point) require an actuator. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.

Prices for Valve
Prices for stainless steel valves are directly co related to prices of the raw materials such as iron ore, metal scrap, chromium, nickel and various other alloying elements. The production cost of heat resistant stainless steel and nickel alloy valve is high as they contain high amount of nickel and chromium. Meanwhile, mild steel material is among the lowest cost steel available, followed by carbon steel, 400 series stainless steels, aluminium, alloy steel, and 300 series stainless steel. Special alloys such as titanium, Inconel, Monel and Hastelloy cost very high as the nickel, chromium and moly content is very high.
