Structure of PCRL pressure regulator - low flow
A:
Analog control circuitry compensates for dynamic changes in output pressure, offering fast, accurate, closed-loop pressure control characteristics.
B:
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.
C:
Relief port can be plugged (with PF fitting), allowing for non-relieving type function.
