Piezo proportional valves

The base component for a wide range of medical technology applications

  • Extremely low electric power consumption (no self-heating)
  • Control starting at 0 bar (vacuum version available)
  • High pressure control stability

Piezo-controlled proportional valve of the Tecno series are 3-way pressure valves and feature integrated electronic pressure control as well as a pressure sensor at the output. Pneumatic output pressure can thus be controlled as a function of an electrical control signal (setpoint value). The pressure sensor measures the instantaneous output pressure, and the electronics control it with high precision and dynamics – at low power consumption. This allows the pressure to be set as a function of the process by way of system control.

HOERBIGER manufactures Tecno valves in automated processes on precision equipment in a clean room environment, using only premium materials. Careful calibration and 100% outgoing inspection of all components as well as traceability of all manufacturing and testing processes assure the user a quality product.
