Electronic ressure regulators

Electronic pressure regulators for high-precision control of pressures up to 6.8 bar. Thanks to integrated proportional valve technology, these controllers enable a fast response time and a very long lifespan of several million cycles. Operation is extremely quiet even at low pressures.

Electronic pressure control - fast and accurate

The proportional valves inside the pressure regulators enable a stepless regulation of the pressure. Due to the fast response times and the low hysteresis of the valves, quick adjustments to the target pressure can be made. The response time of the controller is only one second, with a typical accuracy of +/- 0.5% over the full span.

With an operating voltage of 12 VDC or 24 VDC and a control signal of either 0-5 V or 0-10 V, these systems can be easily integrated into applications in which an pressure must be adjustable.

The two pressure regulators differ in the flow range. The PCRL is suitable for lower flows up to 18 l/min (Cv 0.02) with a stable outlet pressure, the PCRH for larger flows up to approx. 650 l/min (Cv 0.30). Both electronic pressure regulators are optionally available for a pressure range up to 3.4 bar or 6.8 bar.
