Proportional valves for medical devices

Precisely regulating gases with piezo technology

Modern valve technology, such as for ventilator breathing devices, helps to save the lives of many patients. We are well aware of our responsibility and with our portfolio of valves for efficient regulation and control of medical gases and fluids, we offer you exactly the precision and reliability that are needed here – including maximum cost-effectiveness. In addition to solenoid valves, we often use proportional valves with piezo technology for these applications.

Collaborative engineering as a success factor

We work closely with you to bring your ideas for medical devices to life. Our products have been tried and tested in medical devices and can be adapted for your specific requirements. We know the challenges you face and have extensive experience in medical technology, which enables us to offer solutions that are cost-effective, reliable and ready to install.

Our portfolio ranges from standard products that have been tried and tested in existing medical devices to specific designs for medical devices that accelerate the FDA approval process, and we offer design, development and production within an ISO 13485 quality environment.

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 a steady flow, but only to change the state of the flow. This prevents the build-up of heat.

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, conveys liquids or vacuum-extracts them.

Regulation of fluid flows, gas flows and sludge at dental service units

In operation:
Switching valves, proportional valves, pumps and compressors for regulating fluid and gas flows and sludge from different and independent treatment instruments.

Medical equipment

Medical mattresses for hospital beds

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

Suitable products for medical technology

Proportional flow control valve

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

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

Solenoid valve VOVK

At a width of 5.9 mm, the miniature valve VOVK is extremely narrow and can be used wherever the MHA1 is too large. Depending on the type of connection, up to 20 valves can be connected in a row. With a pressure range of up to 7 bar or down to -0.9 bar in vacuum operation, the 3/2-way valve NC VOVK …

Proportional directional control valve

Proportional directional control valve VPWS

Compact and high-performance: Proportional solenoid valve VPWS is a light and compact 15 mm cartridge valve with a high flow capacity. It regulates gas flows safely and precisely – whether this is oxygen, carbon dioxide, air, nitrous oxide or inert gas.

Media separated solenoid valve

Media separated solenoid valve VYKA

With a width of just 7 mm (NW 1.2 mm), VYKA controls very small volumes of fluid (µl, ml) with high precision, even aggressive fluids. The holding current reduction of the plug-in E-box VAVE prevents heating of sensitive media.

Solenoid valve

Solenoid valve MH2, MH3, MH4

Fast-switching valves for higher flow rates.

Proportional-pressure regulator

Proportional-pressure regulator VEAA

For pressure ranges up to 10 bar: piezo technology makes the VEAA extremely precise and gives it a very long service life. Other benefits include extremely short switching times, quiet operation and very low power consumption.

Proportional-pressure regulator

Proportional-pressure regulator VEAB

For pressure ranges up to 6 bar: piezo technology makes the VEAB extremely precise and gives it a very long service life. Other benefits include extremely short switching times, quiet operation and very low power consumption.

Pressure regulator

Pressure regulator LR, LRS

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