Dual Plate Check Valve

Principle：

Dual plate check valves’ design and manufacture according to API 594 and E101 standards of reasonable structure, excellent performance, beautiful shape.

Features：

1. The cavity of the valve adopts pressure self-tightening sealing structure, the higher the medium pressure, the better the sealing performance;

2. The two ends of the branch pipe are welded to meet different requirements of the pipe

3. The sealing surface of valve disc and valve seat is welded by stellite hard alloy, which has good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life;

4. The disc rotates around the pin outside the seat to reduce the impact of closing;

5. Built-in pin shaft structure, reduce leakage point, more reliable use.
