For use with threaded pipe, these valves are available with NPT, NPTF, BSPP, BSPT, UNI/UNF (JIC), and metric connections.

To achieve the maximum possible flow, internal components are designed to reduce flow resistance.

Plastic provides a lightweight alternative to metal.

Rated for up to twice the pressure of standard check valves, these can withstand pressures up to 2,000 psi.

Barbs grip onto tubing, providing a secure hold.

Two sleeves give the fittings extra gripping power. They bite into tubing as you tighten the nut to form a strong seal. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

With internal components that resist wear from frequent operation, these valves can cycle as often as once per second.

To reduce installation time and allow for maintenance without detaching pipe connections, these valves have union fittings.

The most chemical-resistant check valves in our offering, these have a PFA body to withstand methyl ethyl ketone, sodium hypochlorite, and other extremely harsh chemicals.

For more durability than plastic, these valves have a metal body.

These heavy duty valves can withstand pressures up to 1,975 psi and temperatures up to 800° F.

For more than twice the temperature rating of standard check valves for oil and fuel, these have a heat-resistant fluoroelastomer seal that can withstand temperatures up to 500° F.

Valves have NPT connections for use with threaded pipe.

Commonly used with irrigation systems and laboratory equipment, these valves have NPT connections.

A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals.

To automatically shut off the flow of diesel fuel, fuel oil, kerosene, and oil in case of fire, these UL listed valves automatically close and the handle permanently fuses in place when the ambient temperature reaches 165° F.

Stop the reverse flow of gas in your regulator.
