Selection Of Sealing Materials:
Standard configuration:
the elastic parts are made of chromium-nickel molybdenum steel, which has excellent corrosion resistance and better elasticity. The force is reliable and stable. The end face is made of imported graphite ring, non-pressure sintered SiC and other high quality materials.

Common configuration:
On the basis of not affecting the sealing performance, reduce the material grade in the standard configuration, the elastic element can be made of chromium nickel stainless steel, but also has good corrosion resistance and elasticity, reliable and stable force, end face using graphite ring, hard alloy, SiC and other high-quality materials.
