About On/Off Valves

Easy-to-Install Plastic Threaded On/Off Valves

Slide the included union fittings onto your pipe and thread these valves into the fittings—no lengthy installation process required. When it’s time to clean or maintain your line, just unthread the valves from the fittings. Made of plastic, they last longer than metal valves since the inside won’t corrode or pit. They’re also lighter weight than metal valves. With a full port, these valves won’t restrict flow.

Valves with a T-handle have a larger gripping surface than valves with a short lever handle, so they’re easier to turn in slippery environments.

CPVC valves handle higher temperatures than PVC or polypropylene valves. They’re the best choice if your system connects to a heater.

Valves with socket-connect female connectors let you make threaded-to-threaded connections or adapt threaded to socket connections.

Easy-to-Install Socket-Connect On/Off Valves for Chemicals

Union fittings on both ends of these valves disassemble for fast installation and removal from your pipeline. Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. These valves have a fluoroelastomer seal and a plastic body that can withstand aggressive and corrosive solutions in chemical-processing applications. All have a T-handle that resists accidental movement when snagged or bumped. Valves are full port, so they do not restrict flow.

Lockable T-handles can be fixed in place using a padlock (not included) with a shackle diameter up to 1/4”.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Easy-to-Install Threaded Diverting Valves for Chemicals

For easy installation and removal from pipelines, all ends on these valves have union fittings that disassemble into multiple pieces. Their fluoroelastomer seal and plastic body can withstand aggressive and corrosive solutions for diverting flow between ports in chemical-processing applications. In addition to threaded NPT female connections, these valves come with socket-connect (unthreaded) female fittings. All have a T-handle that resists accidental movement when snagged or bumped. They are full port, so they do not restrict flow.

Valves with L-pattern flow direct flow from the bottom-port inlet to either side-port outlet or shut off flow completely.

Valves with T-pattern flow can use any port as an inlet or an outlet. Turn the handle to direct flow from the inlet port to either outlet port at full capacity, direct flow to both outlet ports simultaneously at reduced capacity, or shut off flow completely.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
