![Hayward Needle Valves: Manually Actuated - CPVC \ FPM](/sites/default/files/styles/list/public/images/product/d94dbba26ce0193618228642a22b/NVA%20Series%20Needle%20Valve_PVC.jpg?itok=FLCgZ6rg)
Hayward Needle Valves are used for accurate metering of fluids. Turning the thumb wheel moves a tapered piston into the Teflon® 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. Pressure Rating - 150 psi @ 70°F (non-shock).
