Description

 flap valve

Steel flange lift type check valve

The flap gate is a one-way valve installed at the outlet of the drainpipe for the water supply and drainage works and the sewage treatment works. It is used to overflow or check the medium, and can also be used for various shaft covers. According to the shape, the round door and square patting door are constructed. The flap door is mainly composed of valve body, valve cover and hinge component. It has two kinds of materials, cast iron and carbon steel. Its opening and closing force comes from water pressure and does not need manual operation. The water pressure in the flap door is larger than that at the outside side of the flap door, and it opens. Otherwise, it closes and reaches the overflow and stop effect.
