About On/Off Valves

On/Off Valves with Barbed Fittings for Chemicals
Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a plastic body and a chemical-resistant seal.
T-handles resist accidental movement when snagged or bumped.
Full-port valves do not restrict flow.
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.

- Seal Material: EPDM Rubber
For chemical-processing applications in confined areas, these valves have an EPDM seal and a PVC body to withstand aggressive and corrosive solutions and a low-profile handle to fit in tight spots.
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.
Single-Inlet Sink Faucets
Styles A, B, and C have a 3/4" male GHT outlet which is a standard garden hose connection.
Color-Coded Quarter-Turn Shut-Off
Valves for Hot and Cold Water
Quickly identify hot and cold water lines with these red or blue valves. The low-profile elbow shape and small handle are made to fit into tight spaces, such as plumbing outlet boxes (sold separately). Connect the NH/NST threads to a water hose on a washing machine or commercial plumbing fixture.
Valves with a barbed inlet are compatible with Viega PEX tubing; attach them to your line with a crimping tool and crimping ring (both sold separately).
