Product Description

Forged Steel Manual wafer butterfly check valve

Butterfly check valve is to rely on the flow of the medium itself and automatically open, close the disc, used to prevent the backflow of the medium valve, also known as the check valve, one-way valve, reverse flow valve, and back pressure valve.Check valve belongs to a kind of automatic valve, its main role is to prevent the backflow medium, to prevent the pump and drive motor reversal, and the discharge of the container medium.Check valve can also be used to give the pressure could rise to more than the system pressure of the secondary system supply piping.Check valve can be divided into swing check valve (according to the center of gravity rotation), lifting check valve (along the axis of movement), butterfly check valve (along the center of rotation).
