Compact Threaded On/Off Valves for Chemicals
For chemical-processing applications in confined areas, these valves have an EPDM seal and a PVC or CPVC body to withstand aggressive and corrosive solutions and a low-profile handle to fit in tight spots.
Standard-port valves slightly 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.

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.
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.
