FAQ
Q1: What is a foot valve and what does it do?
A foot valve (or bottom valve) is a specialized type of check valve combined with a strainer, installed at the very bottom of a suction pipe submerged in a liquid source (like a well, tank, or reservoir). Its primary function is to allow liquid to flow into the suction line when the pump operates, but instantly close when the pump stops. This prevents the liquid from draining back out, keeping the suction line "primed" (full of liquid) and protecting the pump from damage due to dry running.
Q2: Is your ductile iron foot valve suitable for firefighting systems?
Absolutely. Its reliability is critical for fire pump suction lines. The ductile iron construction provides the strength and corrosion resistance needed for high-pressure demands and standby conditions. The instant backflow prevention ensures the pump remains primed for immediate emergency response. It's an excellent choice for drafting from ponds, tanks, or reservoirs in fire protection setups.
Q3:Can I request a product sample?
We generally provide free product samples upon request. While we cover the product cost, customers are responsible for associated shipping fees.
Q4:Why choose a foot valve over a swing check valve?
Foot valves are hybrid devices combining:
✓ Check valve function (backflow prevention)
✓ Strainer (debris exclusion)
✓ Submersible construction
Use them only at suction inlets (wells/tanks) to maintain prime and protect pumps. Swing checks suit horizontal/vertical pipe runs where filtration isn't needed – they fail if submerged at source intakes due to debris ingestion.
