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.

Plastic provides a lightweight alternative to metal.

The heat-resistant rubber seal withstands temperatures up to 500° F.

Sandwich these valves between two ANSI flanges for backflow prevention at a fraction of the weight of flanged check valves and a reduced pipeline footprint.

Barbs grip onto tubing, providing a secure hold.

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

Visually inspect flow and debris accumulation through the transparent valve body.

Also known as backwater valves, these valves prevent backflow of sewage and wastewater in drain, waste, and vent systems.

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 insert into a union fitting.

These valves open to allow flow in one direction and close when flow stops or reverses.

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.

Visually inspect flow and debris accumulation through the transparent valve body.

Barbs grip onto tubing, providing a secure hold.

Body is plastic.

The metal body is more durable than plastic.

Sandwich these valves between ANSI flanges.

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.

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.

To maintain sanitary standards in food, beverage, and dairy applications, these valves have sanitary quick-clamp connections and polished internal surfaces for easy cleaning.

Valves have NPT connections for use with threaded pipe.

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

Rated for 12 times the pressure of standard vacuum-breaking valves, these can handle up to 1,500 psi. Connections are NPT.

Integral shutoff valves isolate flow for inline maintenance, and a top-entry cover provides easy access to internal components.

Attach these valves with NPT connections to threaded pipe.

These valves open to allow flow in one direction and close when flow stops or reverses direction.

Prevent air from escaping an air storage tank when the air compressor is not running. These valves open to allow flow into the tank and close when flow stops or reverses direction.

Also known as check valves, these open to allow flow in one direction and close when flow stops or reverses.

These arresters attach directly to torches that cut steel up to 8" thick.

Stop the reverse flow of gas in your regulator.

Stop backward flow in outdoor faucets with garden hose thread (GHT) outlets.
