Valve castings are very common in our daily life, and the materials used are also varied, such as carbon steel, stainless steel, alloy steel, cast iron, etc. Valve body castings can choose gray cast iron as its raw material.Because the shock absorption and lubrication of grey cast iron can satisfy the shock and wear resistance of the valve body.

Some common valve castings have good mechanical properties and performance and play a huge role in our life, such as valve castings, valve body castings, cast carbon steel gate valve, cast iron valves,stainless steel valve etc.

Henan Metals has unique advantages on the manufacturing of valve castings, and is in the leading position in the valve market relying on its strong technical strength and strict product quality.

During the production process of our steel vavles: Henan Metals add the 3.5% water glass sand, (equal to VRH) through this way, the moulds can avoid many disadvantages.For instance, the unstable of the moulds sculpting. And, the craft named compound solidification keeps our moulds almost away from water, thus, the wreck like the pinhole will not existed. So this technique is pretty suitable for the high standard valve and castings, which are used in high temperature, high pressure and extreme low temperature. The sands reusing system can make the water glass sands reusing 100%. So in a way, it brings lots of effects to the environment protection.
