Air Operated Pressure Regulators

Series PRA/PRAM features two opposing large area frictionless rolling diaphragms. Process pressure is applied to one of the diaphragms; air pressure is applied to the other. Because the air pressure can be maintained with more accuracy than the force provided by a spring, the PRA/PRAM offers greater sensitivity and less variance from set pressure than any thermoplastic pressure regulator previously available. The PRA/PRAM can be used in combination with Plast-O-Matic’s patented Stabilizer which measures downstream liquid pressure and provides continuous feedback control for even greater sensitivity and performance. Molded and machined valves in 1/4″ through 3″ and metric pipe sizes in popular thermoplastic materials with a wide range of connection types. Set range 5-125 PSI.
