Plast-O-Matic's Series RVDT automatic valve provides pressure relief, backpressure control and anti-siphon protection

Plast-O-Matic Valves' Series RVDT automatic valve performs multiple functions in a piping system, including pressure relief, backpressure control, pump bypass and anti-siphon protection.

The ½-inch lug-mounted Series RVDT uses an adjustable non-wetted spring to control backpressure in a piping system. The set-point is adjustable, and once the set pressure is reached, the valve begins to open. It will allow the rated full flow at approximately 40% over the set pressure. This operation enables the valve to provide a controlled obstruction in a piping system as needed. It can also be employed to open and relieve pressure in a system. These characteristics enable the valve to remain closed in the event of downstream vacuum, and prevent siphoning of hazardous chemicals.

All wetted materials are thermoplastic; the metal spring is isolated from the process liquid by a PTFE diaphragm. The ½-inch lug-mounted RVDT is offered in body materials of Geon PVC, Natural Polypropylene, Corzan CPVC and Kynar PVDF. Pressure can be set infinitely from 5 to 150 psi.
