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

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

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.

Less than half the end-to-end length of standard flange-mount check valves, these can be installed in pipelines with limited clearance.

Insert tubing into the fitting—no heat, solder, or flux required.

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

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.

Barbs grip onto tubing, providing a secure hold.

Plastic provides a lightweight alternative to metal.

Rated for at least four times the pressure of standard check valves for oil and fuel, these are often used in hydraulic applications with pressures up to 3,000 psi.

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