Screw foot valve H12W-16

A flange bottom valve, also known as a check valve, is a low-pressure flat valve that ensures one-way flow of liquid in the suction pipeline, allowing the pump to operate normally. When the pump stops working, prevent the liquid from returning to the water source tank and ensure that the suction pipe is filled with liquid to facilitate the start of the pump.

This valve consists of valve body, valve disc, valve cover, liner, sealing ring and other parts. Under the pressure of the fluid, the valve disc opens. When the packaged water pump stops working, the return water pressure in the outlet pipe will quickly close the valve disc, and the liquid will not flow back to the water source, playing a role in both smooth pumping and saving water energy loss.
