Product Overview
Dual phase steel wafer check valve is a valve that can automatically reverse flow of fluid. The valve disc of the check valve opens under fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet pressure is lower than the outlet backflow, the valve disc automatically closes under factors such as fluid pressure difference/gravity to prevent fluid backflow. It is widely used in industries such as power plants, chemical engineering, and hydropower.
