Structure of PCRH pressure regulator - high flow

Structure of PCRH pressure regulator - high 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:
Utilizes a pilot operated configuration with an Internal Valve and Diaphragm. This offers high volume flow rates relative to size, while accurately controlling output pressure.
