Designed for highly corrosive and ultra-pure chemicals, this pressure regulator uses compressed air to control pressure with greater accuracy as compared to standard spring-controlled models. Sizes 1/4", 1/2" and 3" are Series PRA; sizes 3/4", 1", 1 1/2" and 2" are Series PRAM.

Pressure regulators provide protection for valuable downstream instruments and filtration systems by converting fluctuating or excessive inlet pressure to a preset maximum downstream pressure. The PRA/PRAM will routinely handle inlet pressure up to 150 PSI and accurately maintain a downstream pressure from 5 to 125 PSI.

The design of the 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. The Stabilizer is described in detail below.
