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

Plastic provides a lightweight alternative to metal.

Rated for up to twice the pressure of standard check valves, these can withstand pressures up to 3,000 psi.

With few moving parts to wear out, these valves withstand frequent opening and closing, pulsating flow, and rapid flow reversal.

For more durability than plastic barbed check valves, these have a stainless steel body.

Weld to unthreaded metal pipe.

Weld these valves to unthreaded pipe for a smooth, flush connection that provides maximum flow.

Body is plastic.

Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection.

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.

To withstand high pressures and temperatures in steam service applications, these valves have a 316 stainless steel body, PTFE ball, and PTFE seal.

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