Why are valves manufactured using a forging process?

What is a forged valve?

Forged valves are produced by shaping and forming the metal in its own solid form. It is done with the use of tools, heat and dies to actually create the valve shape.

How are forged valves made and manufactured?

Valves are made while using the forging method and it helps in involving alloys and shaping metals. The valve body manufacturing technology is based on the multi-dimensional forging process .The forging have good mechanical properties and quality appearance. It can save materials and energy. If your industrial app involve severe conditions and high pressures a forged valve is one of the better option that suits your needs. A forged valve is designed very differently that all other kind of valves and they are typically casted. This article will tell users the manufacturing process and also the reason why choosing the forging process for valve manufacturing.

Reasons valves are manufactured using forging process

Forged valves are better for many applications. If your app is very demanding such as through high pressure and high temperature you should have durable and strong valve solutions. Forged valves are very much stronger than cast valves. The forging process for high temperature valves helps in reducing vulnerability and issues like porosity, shrinkage and cracking. Forged valves are very much better to handle temperature changes. Forged valves are very much reliable, durable and have the lower maintenance that is compared to the casts’ options.

Advantages of using forged valves for manufacturing valves

Forged valves have many advantages for industrial, gas and oil valve manufacturing processes. They are as follows:

1.   It helps in less wasting materials because the flash after second pressing on the valves dies.

2.   Forged valves are very ideal for high temperature systems and for high pressures. It contains great strengths that’s why it is very good for the manufacturing process.

3.   Contains less wall thickness and it ha less chance of thermal fatigues that is during valve working

4.   It contains a great dimensional tolerance because of the thickness of the wall. The uniform tolerance is the biggest advantage of the valve manufacturing forging process.

5.   Distributors have to select high reliability products and high competence.

Forged method is used by some manufacturers

The Manufacturing of the stem, valve bodies and seat are involved in the production process of industrial valves. To produce these parts of valves the casting method is used. The forged method is used by some manufacturers. It involves sandblasting, machining, trimming, forging and surface treatment. A single piece can be used to make the valve bodies. It can also be cast by using mold or cores. A core is used by modern casting processes which helps in producing the parts that have complex inner cavities.


To understand the manufacturing process of valves we should know different steps that are involved. This process consists of many dissolving metals, shaping materials, cleaning up and casting. The final product is processed and it is tested for quality as well as for pressure and temperature.
