Barbs grip onto tubing, providing a secure hold. These valves open to allow flow in one direction and close when flow stops or reverses.
Nylon valves are more impact resistant than PVC or polypropylene valves.
Polypropylene valves are more corrosion resistant than PVC or nylon 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.

With internal components that resist wear from frequent operation, these valves can cycle as often as once per second. Barbed fittings and unthreaded fittings grip onto tubing, providing a secure hold. All valves open to allow flow in one direction and close when flow stops or reverses.
Nylon valves are more impact resistant than polypropylene valves.
Polypropylene valves are more corrosion resistant than nylon valves.

Also known as luer lock couplings, quick-turn fittings consist of a plug and a socket that connect with a half turn, so you can easily connect and disconnect your line. These valves open to allow flow in one direction and close when flow stops or reverses. The clear body allows you to visually inspect flow and debris accumulation.
