Foot valve

1. The Metal foot valve, also known as the check valve, is a low-pressure flat valve. Its function is to ensure the one-way flow of liquid in the suction pipe so that the pump can work normally. When the pump stops working intermittently, the liquid can not be returned to the water source box. The suction pipe is filled with liquid to facilitate the start of the pump.

2. The foot valve can be divided into the plastic foot valve and metal foot valve according to the material, and can also be divided into the ordinary foot valve and foot valve with backwashing flow.

Structural features

The metal foot valve is provided with a plurality of water inlets on the valve cover and is equipped with a screen to reduce the inflow of debris and reduce the probability of blockage of the bottom valve. Although the bottom valve is equipped with an anti-clogging screen, the bottom valve is generally suitable for cleaning media, and the medium with excessive viscosity and granularity should not use the foot valve.
