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.

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

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

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

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

To reduce installation time and allow for maintenance without detaching pipe connections, these valves have union fittings.

Bolt to ANSI flanges.

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