1/4" Hayward NVA Series CPVC Needle Valve w/Threaded ends, FPM O-rings

Needle Valves are used for accurate metering of fluids. Turning the thumbwheel moves a tapered piston into the PTFE seat to control the flow down to a few drops per minute. Precision-molded, fine-pitched stem threads permit this very fine metering flow control.

Available in PVC, CPVC, GFPP and PVDF materials and construction. The NVA Series features an integrated stem with a PTFE seat for superior control, purity and performance. Sizes range from 1/4 inch (DN8) to 1/2 inch (DN10). FPM Seals are standard. All valves carry a pressure rating of 150 psi / 10 bar Non-Shock at 70°F.
