Electronic pressure regulator

Certain pressure control problems involve factors such as remote control, automation, or data collection that require an electronic device. In the past decade, the fastest growing type of electronic pressure regulator (EPR) has been the servo valve design, which uses two high speed servo or solenoid valves to increase or decrease gas pressure as needed to maintain pressure. These EPRs offer higher pressures and more flexibility and robustness than previous technologies, which were often marketed as electro-pneumatic transducers. Servo EPRs work by using a push valve and a vent valve to maintain the outlet pressure at the desired setpoint. A small internal pressure sensor monitors the output pressure and a digital or analog controller adjusts the timing of the servo valves to maintain the set-point.
