How to choose the material of the valve (cast iron, cast steel, stainless steel)

Date:Aug 05, 2019

Our daily common use is cast iron valves (grey cast iron, ductile iron), cast steel gate valves, stainless steel valves, but how do we identify the material of the valve when purchasing the valve? First of all, Henan Jindian Valve Co., Ltd. first introduced the difference of valve material: for example, gray cast iron gate valve type - Z41T-10, ductile iron gate valve type Z41T-10Q, cast steel gate valve type Z41H-10C, stainless steel gate valve type Z41W- 10P. The letter behind the pressure represents the material of the valve.

How to choose the material when the valve is in use

Gray cast iron valves and ductile iron valves are low temperature and low pressure valves, which are generally suitable for use in industrial water supply and drainage mine pipelines;

Cast steel valves are suitable for installation on boiler pipes. The temperature of cast steel valves is 300 °C and the maximum temperature can reach 425 °C. Cast steel valves are suitable for use on some steam pipes.

The stainless steel valve has the function of corrosion resistance and rust resistance, and is suitable for applications in food, pharmaceutical, petrochemical, chemical and other fields.

Through the above general introduction, I believe everyone can understand how the valve should be applied! Instead of choosing a valve, choose the right valve in different areas.
