Valves & Actuation

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).

Hayward True Union Ball Valves are superior performers. A fine-pitch seal retainer thread allows for accurate compensation for seat wear. Reversible seats make it easy to get a damaged valve back in service. Should the seats become damaged, they only need to be removed, turned over, and re-installed to put the valve back on line. These valves feature a double o ring stem seal for twice the leakage protection of valves with only a single stem seal. Hayward’s manual True Union Ball Valve has been designed so that it can easily be converted to an automated valve in the field. To do this, just remove the compression fit handle and install an actuator mounting bracket.
