Check Valves
Available1,445 products
Check valves allow single-direction flow of liquids or gases. Also called one-way or non-return valves, they prevent backflow of downstream media into pumps, residential plumbing systems, and industrial process applications.
PVC Check Valves
PVC (polyvinyl chloride) check valves have corrosion- and chemical-resistant bodies that withstand cold to moderate temperatures.

CPVC Check Valves
CPVC (chlorinated polyvinyl chloride) check valves resist most acids, bases, halogens, oxidants, and salts. They are more flexible and heat tolerant than PVC valves.
Plastic Check Valves
Plastic check valves are resistant to chemicals and corrosion.
Stainless Steel Check Valves
Stainless steel check valves resist corrosion and are suitable for applications with high pressures and temperatures, including steam.
Cast Iron Check Valves
Cast iron check valves have heavy-duty bodies that withstand high temperatures.
Ductile Iron Check Valves
Ductile iron check valves have heavy-duty construction that withstands vibration. Their ductility makes them more flexible and resistant to impact and cracking than cast iron.
Steel Check Valves
Steel check valves are suited for high pressure and temperature applications where corrosion resistance is not a concern.
Lead-Free Brass & Bronze Check Valves for Potable Water
Lead-free check valves have brass or bronze construction to comply with low-lead regulations for use with potable water.
Brass Check Valves for Non-Potable Water Applications
Brass check valves are suited for applications with non-potable water systems. They have strong, malleable bodies that provide better heat and corrosion resistance than plastic valves.
Bronze Check Valves for Non-Potable Water Applications
Bronze check valves resist metal fatigue, corrosion, saltwater, and chemicals and are suited for applications with non-potable water.
