Check Valves with Barbed Fittings for Harsh Chemicals

Prevent backflow in chemical tubing lines. These valves have barbed fittings that grip onto tubing, providing a secure hold. The plastic body and fluoroelastomer seal provide excellent chemical resistance. Valves open to allow flow in one direction and close when flow stops or reverses.
Polypropylene valves are more corrosion resistant than nylon valves.
Nylon valves are more impact resistant than polypropylene valves.
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.
