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

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

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

Plastic provides a lightweight alternative to metal.

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

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

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

Also known as luer lock couplings, quick-turn fittings consist of a plug and a socket that connect with a half turn, so you can easily connect and disconnect your line.

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

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

Solder these valves to copper tubing for a permanent, leak-tight connection.

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.

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

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

The metal body is more durable than plastic.

Body is plastic.

Valves have NPT connections for use with threaded pipe.

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.

Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection.

These compact valves fit into standard sanitary quick-clamp fittings. All are FDA Compliant 21 CFR 177.2600 and have polished surfaces for easy cleaning.

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

Prevent dirty, contaminated water from backing up into your garden hose line—install these valves between a faucet and a garden hose.

Attach these valves with NPT connections to threaded pipe.

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

Put an end to water damage from backed-up sewers. When water backs up, the rubber float will rise to seal off the drain. When water recedes, the float will drop for normal drainage.

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

Stop the reverse flow of gas in your torch.

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