 Structure of PCRL pressure regulator - low flow

Structure of PCRL pressure regulator - low flow

Analog control circuitry compensates for dynamic changes in output pressure, offering fast, accurate, closed-loop pressure control characteristics.

The incorporation of two proportional control valves offers fast and smooth pressure control, excellent resolution, as well as optimized response times when pressure venting, and reduced overall air (media) consumption.

Relief port can be plugged (with PF fitting), allowing for non-relieving type function.
