WAFER check valve is a general one-way valve for fluid.Lightweight, small-sized, WAFER check valve iseasy to install between the flange.

The interior of the valve consists of two semi-circular taut springs and plates that fixed to the valve body with a pin. Moving fluid make the spring deform and get through the valve. The valve closes when the spring lose fluid pressure. The spring deforms quickly, which keeps the pipeline from the damage of water hammer.
