Cast iron foot valve
The bottom valve, also known as the check valve, is a low-pressure flat valve. Its function is to ensure the one-way flow of the liquid in the suction pipe to make the pump work normally. When the pump stops working for a short time, the liquid cannot return to the water source tank to ensure water absorption. The tube is filled with liquid. There are many water inlets and reinforcing ribs on the valve cover, which are not easy to be blocked, and are mainly used in the pipeline for pumping water. Widely used in sewage treatment, petrochemical, mining smelting, water conservancy and power industries.
