Compact, quiet, energy-efficient valves with piezo technology in medical technology

 의료 분야에서도 기기의 소형화, 경량화, 저전력에 대한 요구가 높아지고 있습니다. 피에조 밸브와 소형 밸브 MH는 의료 기기의 소형화에 맞는 이상적인 솔루션입니다. 특히 피에조 밸브는 기술적으로 우수한 점이 많기 대문에 의료 분야에서의 밸브에 요구되는 기능에 적합합니다.

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

control the flow rate, e.g. in mobile oxygen therapy devices, thus ensuring precise oxygen supply and dosing during inhalation.

3/3-way proportional valves

are used, e.g. to regulate the flow or pressure in oxygen therapy, ophthalmology or dialysis.

Proportional valves

Proportional valves VEMR and VEAE

Choice of various valve series with different working pressures, nominal widths, flow ranges and working temperatures:

Treatment systems

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

수술 도구

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.

의료 기기

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.

Smaller, lighter and quieter

In the field of medicine too, there is a growing demand for smaller and lighter equipment. Piezo valves and miniature valves MH are the ideal solution for small flows in medical technology.

Thanks to their great technical features, piezo valves are particularly well suited to valve functions in the field of medicine:

  • Piezo valves are noise free: essential for equipment used by patients throughout the night.
  • Piezo valves don't use much energy: the equipment doesn't have to be charged up as frequently.
  • Piezo valves do not generate any heat: the equipment is smaller and safer during operation.
  • Piezo valve operation is proportional: meaning the equipment can be continuously switched, e.g. when administering oxygen doses in breathing apparatus.


For applications with a large number of pneumatic connections in a very small space, Festo delivers customised and ready-to-install manifold duct plates.

Support with breathing

Equipment for respiratory disease therapy

Medical technology

Oxygen therapy

Oxygen dosing for illnesses involving chronic oxygen deficiency

Festo develops solutions for controlling the amount and concentration of oxygen supplied to the breathing air. These systems are integrated into the customer's medical product, e.g. mobile oxygen equipment.


Application example – Oxygen equipment

Medical technology

Sleep apnoea

Reduced oxygen supply due to respiratory arrests during sleep

Continuous Positive Airway Pressure (CPAP):
providing slightly positive pressure (excess pressure) facilitates breathing and prevents apnoea.



Festo develops solutions that regulate the pressure and flow of the inhaled air/oxygen, thereby ensuring that positive pressure is constantly supplied for breathing. These solutions are integrated into the customer's medical product.
