The check valve by the pressure of the media to achieve the valve between the valve and the valve seal, the greater the medium pressure, the better the sealing performance. Valve cavity at any time to withstand the pressure of the pipeline.

The valve body is made of alloy steel, which has strong mechanical properties and safety and reliability.

Connected with the valve body and valve cover by bolt of check valve, the seal ring is steel. So that the valve cover and the valve clearance is very small (0), thus effectively reduced corrosion medium on the screw bolt and a screw hole corrosion and bolt load.

In addition, the valve core and valve sealing surface welding hard alloy, so that it has a good resistance to erosion and corrosion resistance. The valve core material adopts sulfur proof steel, so it can be used in the environment containing H2S.
