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.
Polypropylene valves offer good heat resistance. Use them in systems that connect to a heater.
Lever handles show the valve’s position. T-handles resist accidental movement when snagged or bumped.Valves with tapered barbs can be used with multiple tube sizes.
Standard port valves slightly restrict flow. 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.

Compact Threaded On/Off Valves for Chemicals
For chemical-processing applications in confined areas, these valves have a low-profile handle to fit in tight spots. A rubber seal and a plastic body stand up to aggressive, corrosive solutions.
Polypropylene valves are the most chemical resistant. They handle a wide range of acids, solvents, and other harsh substances.
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.
