Socket-Connect Check Valves

Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection. These valves open to allow flow in one direction and close when flow stops or reverses. The valve body is 316 stainless steel for excellent corrosion resistance. A removable cap provides easy access to internal components for maintenance.

Socket-Connect Check Valves for Drinking Water

Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. These valves meet NSF/ANSI 61, which means they’re safe to use with drinking water. They open to allow flow in one direction and close when flow stops or reverses.

PVC Body—Spring-Loaded Piston

Spring-loaded piston check valves reduce slamming and vibration in quick shut-off applications.

Solder these valves to copper tubing for a permanent, leak-tight connection. They meet NSF/ANSI 61 for use in drinking water lines. All open to allow flow in one direction and close when flow stops or reverses.

Two-Stage Backflow-Prevention Valves with Solder-Socket Fittings

Solder these valves to copper tubing for a permanent, leak-tight connection. They have two integral check valves with a vent between them for maximum protection from system contamination. If the primary check valve fails to close when flow stops or reverses, overflow is discharged through the threaded vent and the secondary check valve prevents backflow. Attach the vent to drain pipes to prevent spillage. These valves are designed for applications with continuous flow and are commonly used on water supply lines to boilers, processing tanks, and other equipment. All have an integral strainer to prevent debris from blocking the check valves.

Plastic Socket-Connect Check Valves

Also known as backwater valves, these valves prevent backflow of sewage and wastewater in drain, waste, and vent systems. Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. Valves open to allow flow in one direction and close when flow stops or reverses. A removable cap provides easy access to internal components for maintenance.
