Bolt to ANSI flanges.

With a shorter end-to-end length than other check valves, these fit in tight spaces.

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

At 1 1/2" long or less, these valves fit in confined spaces.

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

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

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.

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

Barbs grip onto tubing, providing a secure hold.

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.

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

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

Body is plastic.

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.

Plastic provides a lightweight alternative to metal.

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

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

Release pressure in the line between a compressor and an air storage tank, making start-up easier on the motor. These valves open to allow flow into the tank and close when flow stops or reverses direction, preventing air from escaping the tank when the air compressor is not running.
