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.
