Electronic Pressure Regulators
Electronic pressure regulators translate digital or analog signals into a variable output pressure. These devices typically operate on air on inert gases. Though they typically have limited flow capacities, some models have volume boosters for higher flow rates.
These devices can also be called pressure transducers, electro-pneumatic transducers, current-to-pressure transducers (I/P), voltage-to-pressure transducers (E/P), and pressure control valves, etc.
Equilibar is proud to represent Proportion-Air line of electronic pressure regulators, which include the ultra high resolution QPV line, as well as the QB1 and GP1 with direct pressure control up to 1000 psig.

One of the original tasks of electronic pressure regulators was to command the position of pneumatically actuated control valves. EPRs can also be paired with dome-loaded pressure regulators to command the pressure and flow rate of process liquids and gases.
There have been many different technologies used in electronic pressure regulators over the past six decades. The simple current-to-pressure transducer, which used a simple speaker coil, dominated the golden age of pneumatics in the post-World War II era. Today, most modern electronic pressure regulators use some form of servo valves to push and vent the pressure (how modern EPR's work).
