Proportional valves for medical devices

Control gases precisely

We develop products and systems for medical technology in close partnership with customers. The focus is on efficient regulation and control of medical gases and fluids. In addition to air solenoid valves, we often use proportional valves with piezo technology for these applications.

Optimal for medical technology: proportional valves with piezo technology

Piezo valves are suitable for controlling the pressure and flow rate of medical gases in mobile and patient-oriented applications because they are highly compact, silent and energy-saving. Thanks to the material properties of piezo ceramics, no energy is needed to maintain a constant flow, only to change the flow status. This prevents heat buildup.

Treatment systems

Oxygen therapy for mobile applications

In action:
Small and lightweight piezo valves regulate the gas flows and pressures that dispense oxygen in infinitely variable steps.

Stationary ventilation in clinical environments

In action:
Proportional valves control flow rate and pressure.


In action:
Piezo valves, media valves, pneumatic valves and proportional pressure control valves regulate and control fluid flows from the blood and dialysate stream.

Surgical tools

Eye surgery

In action:
Pneumatic control unit consisting of air solenoid valves and piezo valves drive surgical tools, conveys liquids or suctions liquids with the aid of a vacuum.

Closed-loop control of fluid and gas flow on dental service units

In action:
Switching valves, proportional valves, pumps and compressors for regulating fluid and gas flows various independent treatment instruments.

Medical equipment

Medical mattresses for hospital beds

In action:
Piezo valves actuate chambers individually to regulate gas flow or pressure, quietly and efficiently.
