Microelectronics and semiconductor industries

Critical fluid handling

GEMÜ has been producing ultra-pure valves, measurement and control systems since 1988.

Cleanroom plant in Emmen

All products and components for sanitary/hygienic applications in these industries are manufactured under cleanroom conditions. Using the latest technologies and processes, valves and measurement and control engineering equipment are injection moulded, cleaned, assembled, tested and packaged in cleanroom conditions at the Emmen site in Switzerland.

Areas of application include optics, medicine, photovoltaics, electronics and microelectronics, semiconductor production, the pharmaceutical industry, biotechnology and gene technology, as well as precision mechanics and micromechanics.

Resistant body materials for further areas of application

For critical fluid handling in other industries, the product range can be ordered with body materials such as PTFE, PVDF, PFA or PP, as well as HPS versions (not manufactured in a cleanroom). GEMÜ thereby offers the greatest chemical resistance at a market-compatible price.

Customized system solutions for dosing, control and distribution tasks

Our customized, multi-functional multi-port valves in the GEMÜ iComLine series are suitable for open/closed automatic control systems. The globe diaphragm technology enables short, fast cycles of dosing and control functions, also with aggressive and particulate media. Pressure measurement systems as well as fittings and tubes are also available. These can be ordered separately or supplied fitted to manifolds in accordance with specifications.

Examples of processes employing GEMÜ valves, measurement and control systems 

  • Manufacture of solar wafers and flat panels
  • Dosing of chemicals 
  • Printed circuit board and microchip production 
  • Production of LEDs 
  • Metal deposition

Range of products

All GEMÜ valves with pneumatic or motorized actuator are available with instrumentation ex works.
