How It Works

EPR 500 High Precision Electronic Pressure Regulator

How it Works

Two valve pressure controllers include a “fill” and “vent” valve. Outlet pressure is sensed and controlled through a type of PID loop. While many industrial pressure controllers utilize binary fill and vent valves, or analog fill valves with binary vent valves, the EPR-500 uses two analog valves for highly precise and resolute control throughout the entire range.
