Kelly Pneumatics, Inc. offers a reduced cost, single or dual-valve design, Electronic Precision Pressure Regulator with I/P transducer control circuitry. Designed specifically for high volume flow rates, this regulator precisely controls both positive and negative outlet pressure ranges, even during dynamic changes in outlet flow rates. By utilizing either an externally supplied dynamic/static input signal or an on-board adjustable set-point value, the High Flow Precision Regulator provides exceptional closed-loop, proportional, output pressure control characteristics. This product can be further customized to include a wall adapter connection for power supply, an inline filter, and a mechanical gauge.

Our regulators offer significant improvements over traditional dual on/off valve electronic regulators. Utilizing our patented proportional valve design for both internal fill and dump valves gives a smooth and accurate output pressure, as opposed to dual on/off valve designs that cause substantial shock waves in the regulated pressure signal. The KPI regulator can replace manual regulators, needle valves, and bleed valves or bleed orifice discreet component systems.
