Principle of Foot Valve

The water of the water source enters the valve body from the cover. Under the pressure of the fluid, the disc opens the water, and when the pressure in the outlet pipe stops, the disc will be closed quickly, and the liquid will not be poured back to the water source, which plays a role of unimpeded pumping and saving water energy loss.

Installation and Commissioning of Foot Valve

Installed at the bottom of the pump suction pipe to ensure its vertical status;Start immediately after the water is filled in the forward water pipe for the first time, resulting in a semi-vacuum in the suction pipe and water is sucked into the vertical pipe to complete the water pumping process.
