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

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

Bolt to 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.

Install these valves between ANSI flanges.
