Butterfly Double Flap Check Valve

Butterfly Double Flap Check Valve

Butterfly double-flap check valve depends on the flow of the medium itself and automatically open and close the valve flap, used to prevent the medium backflow and water hammer effect;

The two flaps rotate around the center valve axis, like two sliding doors, and at the same time is equipped with a spring, boosting the two flaps to the direction of the valve closure movement;

Butterfly check valve has a simple structure, can only be installed in the horizontal pipeline, and the sealing is relatively poor, the use of its sealing requirements are not high;

Applicable to urban, industrial and high-rise building water supply and drainage pipeline network, the structure length is shorter than the rotary check valve, installation is more convenient.
