Plast-O-Matic Valves, Inc. (Cedar Grove, NJ) has introduced a new automatic valve that performs multiple functions in a piping system, including pressure relief, backpressure control, pump bypass, and anti-siphon protection. The new ½ inch, lug-mounted Series RVDT uses an adjustable non-wetted spring to control backpressure in a liquid piping system. The set-point is adjustable, and once the set pressure is reached, the valve begins to open. All wetted materials are thermoplastic and pressure can be set infinitely from 5 to 150 PSI. The valves are 100 percent manufactured in the U.S. and can be factory modified for special applications.
