Weld these valves to unthreaded pipe for a smooth, flush connection that provides maximum flow.

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

Body is plastic.

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

The metal body is more durable than plastic.

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

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

Integral shutoff valves isolate flow for inline maintenance, and a top-entry cover provides easy access to internal components.
