Duplex steel check valve has good plasticity and toughness, good thermal conductivity, small coefficient of linear expansion, small welding stress and deformation, and high strength and resistance to chloride ion stress corrosion ...
The body of the 2520 stainless steel check valve is all made of 0Cr25Ni20 material, which corresponds to the American ASTM standard: 310S and the American UNS standard: S31008. It is an austenitic chromium-nickel stainless steel with good oxidation resistance ..
The main parts of the C4 stainless steel check valve, such as the valve body, bonnet, clapper, and valve stem, are all made of high-silicon ultra-low carbon austenitic nitric acid-resistant stainless steel. Its Chinese chemical name is 00Cr14Ni14Si4. The main alloy composition of this material is Cr ..
The main parts of the dual-phase steel vertical check valve, such as the valve body, bonnet, and disc, are made of dual-phase stainless steel. The ferrite phase and the austenitic phase each account for about half of the material. Generally, the content of the small phase is not low. 30%, so it has strong resistance to hydrogen sulfide and chlorine ..
310S vertical check valve is also known as 2520 heat-resistant steel check valve. Its main parts such as valve body, bonnet and valve disc are made of austenitic heat-resistant stainless steel 310S (0Cr25Ni20). The material is high chromium nickel austenitic stainless steel. Oxidation:
Duplex steel swing check valve, also known as seawater chloride ion check valve, is a stainless steel check valve developed by our company to meet the needs of resistance to hydrogen sulfide and chloride ion corrosion conditions. It can automatically prevent the fluid from flowing backward.
C4 stainless steel rotary check valve is also known as special check valve for concentrated nitric acid. It adopts a built-in swing arm swing check structure. All opening and closing parts are installed inside the valve body and do not penetrate the valve body. There are no leakage points outside the gasket and seal ring ..
Chromium molybdenum steel check valve is a lift check valve, including main parts such as valve body, valve cover and valve disc. All of them are made of chrome molybdenum steel or chrome molybdenum vanadium steel. This material is especially suitable for high temperature and high pressure working conditions. Environment, the check valve disc is seated on the valve body.
H42N vertical gas check valve is a device mainly installed on vertical pipelines to prevent gas from flowing backwards. It uses the fluid pressure difference and its own weight to lift the valve to open and close the valve.
