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).
