Check valve by the pressure of the media to achieve the seal between the spool and valve body, the greater the pressure medium, the better the sealing performance. Valve chamber under line pressure at all times.
This body is made of alloy steel forgings for processing, with strong mechanical properties, can withstand high pressure, with safe and reliable performance.
Valve cover and valve body with bolts, seals for the valve cover gasket and the body wall seal, seal and reliable performance. It makes the valve cover and valve body assembly space is small (designed as 0), thus reducing the corrosive medium on the bolts and the holes are erosion and reduce the bolt load.
Spool and the valve sealing surface is welded carbide, so that it has good wear resistance and corrosion resistance, anti-sulfur steel valve material used, other ways to hardness of parts with limited, so the valve can be with H2S in environment.
