To achieve the maximum possible flow, internal components are designed to reduce flow resistance.

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

With few moving parts to wear out, these valves withstand frequent opening and closing, pulsating flow, and rapid flow reversal.

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

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

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

Body is plastic.

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

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.

To withstand high pressures and temperatures in steam service applications, these valves have a 316 stainless steel body, PTFE ball, and PTFE seal.

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.

To prevent flashback in flammable gas pipelines, an internal flame-arresting element absorbs the heat from a fire to extinguish the flame.
