Proportional valves for medical devices

Precisely regulating gases

We develop products and systems for medical technology in close partnership with customers. The focus therefore is on efficiently regulating and controlling medical gases and fluids. In addition to solenoid valves, we often use proportional valves with piezo technology for these applications.

Perfect for medical technology: proportional valves with piezo technology

Piezo valves are ideal for regulating the pressure and flow of medical gases in mobile applications and those close to the patient because they are extremely compact, quiet and energy-efficient. Thanks to the material properties of piezo ceramics, no energy is needed to maintain the current flow, but only to change the flow state. This prevents heat build-up.

Treatment systems

Oxygen therapy for mobile applications

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

Stationary ventilation in a clinical environment

In operation:
Proportional valves regulate the flow and pressure.

Dialysis

In operation:
Piezo valves, media valves, pneumatic valves and proportional pressure regulators regulate and control the flow of fluids from the blood and dialysis circuit.

Surgical tools

Eye surgery

In operation:
A pneumatic control unit consisting of solenoid valves and piezo valves actuates the surgical tools, pumps liquids or extracts them using vacuum.

Regulation of fluid flows, gas flows and slime at dental stations

In operation:
Switching valves, proportional valves, pumps and compressors for regulating fluid and gas flows of the different treatment instruments.

Medical equipment

Medical mattresses for hospital beds

In operation:
Piezo valves control the chambers individually to regulate the gas flow or pressure, quietly and with a soft-start function.

Suitable products for medical technology

Proportional flow control valve VEMD

The dynamic and lightweight mass flow controller VEMD operates extremely quietly thanks to piezo technology. The integrated electronics and sensor record, control, and meter the flow rate of air and inert gases proportionally.

Piezo valve VEMP

Lightweight and small piezo valve for proportional control of pressure or flow rate. Ideal for use in mobile devices, e.g. in medical technology. When combined with a sensor, it can be used as a control valve.

Solenoid valve MH2, MH3, MH4

Fast-switching valves for higher flow rates.

Proportional-pressure regulator VEAA

For pressure ranges up to 10 bar: piezo technology gives the VEAA high precision and an extremely long service life. Other benefits include: extremely short switching times, noiseless operation and very low power consumption.

Proportional-pressure regulator VEAB

For pressure ranges up to 6 bar: piezo technology gives the VEAB high precision and an extremely long service life. Other benefits include: extremely short switching times, noiseless operation and very low power consumption.

Pressure regulator LR, LRS

Sturdy control valve with or without safety lock against unauthorised adjustment.

Satisfied customers with automation from Festo

Mobile oxygen system devices improve the mental and physical ability of patients as well as their quality of life

In practice

Improved quality of life

Around 600 million people worldwide are afflicted with chronic obstructive pulmonary disease (COPD). Mobile oxygen system devices improve the mental and physical ability of patients as well as their quality of life. Japanese company Musashi Medical Laboratory supplies easy-to-operate regulators in smartphone format for these oxygen system devices, thus significantly improving comfort and handling for patients. Compact piezo valves from Festo provide for quiet oxygen supply.

Technical assistant of choice for eye surgeons: The QUBE pro takes individual working methods into consideration and has a dual linear control pedal.

In practice

Precision in eye surgery

Nowadays, cataract surgery is a routine procedure. This is in part due to the pioneering developments in medical technology from companies such as BYTEC, which produced the “QUBE” to support eye surgeons deliver precise and faultless treatment. Piezo, proportional and fast-switching valves allow the necessary rapid incisions to be made.
