Proportional back-pressure regulator PRE series

for airmembranesingle-stage

Piezo-operated proportional pressure valve based on the principle of a piezo element which bends when voltage is applied. At the end of the piezo element is a flapper valve, which operates against a precision nozzle to create back pressure on the control diaphragm of a booster relay. A pressure transducer provides feedback of the outlet pressure compared with the setpoint value with correction by the electronic control system if necessary. Minimal_power_consumption: - no self-heating, even none at pressure absence - safe battery operation over a long period Piezo_element: - almost no power consumption necessary for regulation - extremely quick regulating operations - low-noise regulation especially for medical and laboratory technology Small_and_light_design: - particularly suitable for portable devices in conjunction with battery operation - ideal for limited space conditions Supply_voltage: 24 V DC +/- 10% PRE1: monitor signal optionally 0...P2max, = 0...10 V, max. 1 mA, Ra > 1kΩ PRE2: monitor signal standard 0...P2max, = 0...10 V, max. 1 mA, Ra > 1kΩ
