What is a Foot Valve?
Various
types of valves are required to maintain optimum function of water and
air pumps, and among these valves are foot valves. Foot valves are used
to prime up a centrifugal pump; they are known for their efficacy and
affordability.
Description
Foot valves are a type of check
valve and are placed at the pump’s wet well. Unlike other valves, a foot
valve is created with a larger flow area than the actual pipe size to
make sure that there is less head loss. Foot valves are either made of
PVC plastic or stainless steel, and they are known for keeping the
continuous presence of suction within the pump.
Function
Foot
valves are used to maintain hydraulic pressure to keep the water flow in
accordance with the given settings or configurations. There are
instances where the pressure can actually pop the valve out and cause
major leakage; thus, it is important to use the right kind of material
in the tubing to be able to support the force within the valve.
