High-Pressure Check Valve With New Technology For Disc Protection

The high-pressure check valve designed by Dazhong Valve Group with a new technology for disc protection is installed on the sewer pipe as a safety device to automatically prevent the backflow of the medium. The valve disc is protected by multi-layer electroplating, and the sealing surface on the valve seat is made of drill-based cemented carbide plasma spray welding.

• Installed on the sewer as a safety device to automatically prevent the backflow of the medium.

• The valve disc is protected by multi-layer electroplating, and moves up and down in the guide bushing on the valve cover. When the medium flows back, the valve disc is automatically closed by the medium pressure.

• The sealing surface on the valve seat is made by plasma spray welding of drill-base cemented carbide, which has good wear resistance and scratch resistance.

• The check valve should be installed vertically on the horizontal pipeline, and the medium flow direction is positive flow from bottom to top.
