Basic information of Foot Valve
This valve is installed at the bottom of the pump's underwater pipette, restricting the return of the liquid to the water source in the pump pipe. Dof960 series of cases
Features of Foot Valve
1. Full pipe size flow area;
2. Lowest head loss;
3. 360° stainless steel strainer;
4. The disc is completely covered with adhesive and reliable sealing.
2. 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.
