Valves & Actuation

Hayward TB Series: Manually Actuated - PVC \ FPM

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.

Manual Hayward Three-Way Ball Valves come standard with a two port “TW” ball allowing for three flow configurations within 180˚ of rotation. With the bottom port as the inlet, the flow can be directed to the right or left port, or shutoff. On manual or actuated valves, and optional “TP” ball allows flow through all ports at the same time or flow shutoff. True Union design makes these valves very easy to maintain by allowing for easy removal from a piping system without breaking downstream connections.

Series RVT is an angle pattern design featuring a non-sticking Teflon® shaft passing through three U-cup seals. Venting between the upper and center U-cups results in Plast-O-Matic’s patented Fail-Dry® design for added protection. In the meantime the third seal continues to protect the control spring. The RVT design starts with 1/2" pipe size and runs through 2". Set pressures from 5 to 100 PSI. Once the relief valve is set, the valve will remain closed as long as the tank or line pressure does not reach the set pressure. The valve will begin to relieve when the set pressure is reached and will require an overpressure of approximately 40% to fully open. When the pressure falls below the set pressure, the valve will again close. Series RVT relief valves are constructed of Type 1, Grade 1 PVC, CPVC, Polypropylene, Teflon® or PVDF with solid Teflon® shaft. U-cup seals are EPDM or Viton®. The adjusting bolt, lock nut, control spring and fasteners are cadmium-plated steel. Stainless steel is available as an option.
