Plastic Threaded Flow-Adjustment Valves

For a lightweight and corrosion-resistant alternative to metal valves, these have a plastic body. They gradually open and close with multiple turns of the wheel handle to adjust and regulate flow. All have a rising stem that lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off.

Flow Coefficient (Cv)—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.

Plastic Socket-Connect Flow-Adjustment Valves

Insert unthreaded pipe into the socket ends and bond with PVC primer and cement to create a permanent, leak-tight connection. These valves gradually open and close with multiple turns of the wheel handle to adjust and regulate flow. They have a rising stem that lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off.
