November 3, 2016—Equilibar introduced the EPR-3000 high pressure electronic controller, which offers electronic pressure control up to 3000 psig. It is especially useful for research applications involving catalyst reactors.
The EPR-3000 does not bleed gas when at a steady state pressure, thus preventing the loss of expensive gases through unnecessary exhaust. It features dual proportional valve construction, with one solenoid valve functioning as the inlet to raise pressure and the second acting as the exhaust to decrease pressure by venting.
Using two proportional solenoid valves is key to the high resolution control achieved by the EPR-3000. Electronic control is available through digital or analog communications. Alternatively, manual control is achieved through the front keypad and push buttons. The EPR-3000 is designed for static or low-flow applications of non-corrosive gases.
One key application of the EPR-3000 is to provide a high pressure pilot signal for dome-loaded regulators, making it possible to precisely control conditions even with highly varying process flow rates.
