Main Materials For General Valves

- Aug 17, 2020-

The classification of valves is mainly divided into use and structural characteristics. But generally we use the general classification method that is divided by principle, function and structure. This method is currently the most common classification method at home and abroad. According to the different materials of the valve body, the valve can be divided into:

 

(1) Metal material valve: its valve body and other parts are made of metal material. Such as cast iron valve, carbon steel valve, alloy steel valve, copper alloy valve, aluminum alloy valve, lead alloy valve, titanium alloy valve, Monel alloy valve, etc.

 

(2) Non-metallic material valve: its valve body and other parts are made of non-metallic material. Such as plastic valve, pottery valve, enamel valve, FRP valve, etc.

 

(3) Metal valve body lining valve: The valve body is made of metal, and the main surfaces in contact with the medium are lined, such as rubber-lined valves, plastic-lined valves, and ceramic-lined valves.

 

Valve body materials mainly include: C carbon steel, I1Cr5Mo chromium molybdenum steel, HCr13 series stainless steel, K malleable cast iron, L aluminum alloy, P0Cr18Ni9 series stainless steel, PL00Cr19Ni10 series stainless steel, Q ductile iron, R0Cr12Ni12Mo2 series stainless steel, RL00Cr17Ni14Mo2 series stainless steel, S plastic, T Copper and copper alloys, Ti titanium and titanium alloys, V chromium molybdenum vanadium steel, Z gray cast iron.
