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.


- Valve Type: Stop Cock
- For Use With: Air, Carbon Dioxide, Deionized Water, Ethylene Glycol, Isopropyl Alcohol, Mineral Spirits, Natural Gas, Oxygen, Phosphoric Acid, Soap Solutions, Sodium Hydroxide
- Seal Material: EPDM Rubber
- Seat Material: EPDM Rubber
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.
