Cast Iron Foot Valve

Cast iron foot valve, Material: cast iron; Nominal diameter: DN50-DN600; Nominal pressure: 0.25Mpa-2.5Mpa; Connection: flange connection; Form: automatic; Main function: to prevent the medium backflow; Applicable medium: water system; Use temperature: ≤ 50 ℃. Water from the valve cover into the valve body. Under the action of fluid pressure, the valve flap to open the water, when the indication of stopping the pressure in the outlet pipe will valve flap quickly closed, the liquid will not fall back to the water source, played a smooth pumping and save the role of water loss.

Overview

Application:

Foot valves are equipped with multiple inlets on the valve cover and a screen to reduce the inflow of debris and reduce the chances of clogging of the foot valve. Although the foot valve is equipped with anti-clogging screen, but the foot valve is generally applicable to clean media, viscosity and particles over the media should not use the foot valve.

Foot valve is mainly used in non-self-flooding centrifugal pump pumping occasions, installed in the bottom of the suction line, completely submerged in water. Foot valve has a check function, the water in the suction line can only flow in the direction of the pump inlet, can not return to the suction pool, the first time the pump needs to be flooded to start, and then do not need to be flooded (in fact, due to the sealing of the foot valve, the processing quality, and then need to make up for a certain amount of water to start).
