Festo, in close cooperation with its customers, develops products and subsystems for medical devices.
Focus on efficient regulation and control of medical gases
- Flow control with compact valves for ventilation and oxygen therapy
- Pneumatic integration solutions for surgical devices
- Closed-loop control of fluids in dental stations
Compact, quiet, energy-efficient valves with piezo technology in medical technology
Piezo valves with proportional technology are often better than solenoid valves for mobile applications and applications in close proximity to the patient, especially for flow and pressure regulation:
- Ideal for battery-operated devices thanks to their low energy consumption
- Long service life as the design is very wear-resistant
- Small installation space and low weight
- Compatible with oxygen
2/2-way proportional valves
3/3-way proportional valves
are used, e.g. to regulate the flow or pressure in oxygen therapy, ophthalmology or dialysis.
Proportional valves
Choice of various valve series with different working pressures, nominal widths, flow ranges and working temperatures:
- 2/2-way valve (normally closed)
- 3/3-way valve (normally closed)
Proportional solenoid valve VPWS
Lightweight, compact 15 mm cartridge valve with high flow rate.
- 2/2-way valve
- Ideal for applications with minimal installation space
Pressure regulators and flow control valves with piezo technology, sensors and electronic control
Proportional flow control valve VEMD

Oxygen therapy for mobile applications
In action:
Small and lightweight piezo valves regulate the gas flows and pressures that release oxygen in infinitely variable steps.
Stationary ventilation in a clinical environment
Precise regulation and control of fluid flows from the blood and dialysate stream are crucial when it comes to efficient dialysis.
In action:
Piezo valves, media valves, pneumatic valves, proportional pressure regulators
Surgical tools
An example from eye surgery shows pneumatically operated surgical tools being controlled.
In action:
Pneumatic control unit comprising solenoid valves and piezo valves for the following functions:
- Actuating surgical tools
- Vacuum-supported extraction
- Conveying fluids
Closed-loop control of fluid flows, gas flows and slime at dental stations
The various instruments are controlled independently of one another by switching valves, proportional valves, pumps and compressors.
Medical equipment
Training torsos in medical training simulate breathing, pulse and bodily fluids, such as tears.
Intelligent control systems are used for simulating air and fluid movements.
Regulation of gas flows and pressures in medical mattresses for nursing beds.
Piezo valves actuate the chambers individually – quietly and with a soft-start function.
