HANFLO Foot Valve does not restrict inflow
and will allow the pump to work at its maximum
performance based on pipe size and friction loss.
Pump performance and priming can be strongly
enhanced. HANFLO Foot Valves are highly
engineered to maintain prime in the suction (intake)
line, while providing unrestricted inflow when
the pump calls for water. Where other valves
can restrict inflow by more than 1/3, the HANFLO Foot
Valve allows unobstructed, full flow to the pump
enhancing pump performance.
