About Backflow-Prevention Valves

High-Flow Threaded Check Valves

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

High-Cycling Threaded Check Valves

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

Check Valves with Solder-Connect Fittings

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

Clear-View Socket-Connect Check Valves

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

Socket-Connect Check Valves

Weld to unthreaded metal pipe.

Plastic Socket-Connect Check Valves

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

Clear-View Socket-Connect Check
Valves for Harsh Chemicals

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

High-Performance Threaded Check Valves for Fuel

These heavy duty valves can withstand pressures up to 1,975 psi and temperatures up to 800° F.

Socket-Connect Check Valves for Oil and Fuel

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