PRE

Piezo-operated proportional pressure regulator 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%
