Pneumatic 2/2-way diaphragm valve made of metal

GEMÜ D41

ConfigureTechnical data sheet
Stainless steel diaphragm valve with seal and diaphragm for precise control of flows in industrial applications.

Powerful diaphragm valve with EasyLock technology

Product information

The pneumatically actuated GEMÜ D41 diaphragm valve is designed for use in sterile applications. The diaphragm hermetically separates the actuator from the operating medium. The GEMÜ D41 valve with EasyLock technology is mounted completely without any loose components via a central gearbox. All drive parts (except the sealing and design elements) are made of stainless steel. Normally Closed, Normally Open and Double Acting control functions are available.

Key features

  • Suitable for use in hygienic and aseptic applications (CIP/SIP capable)
  • Fast, safe and simple diaphragm and actuator mounting via a central gearbox due to EasyLock technology
  • Low maintenance thanks to the encapsulated diaphragm, which requires no retightening
  • Very high Kv values due to flow-optimised valve body
  • Identification of the mounting angle (hash mark)
  • Optical position indicator and transparent cap as standard
  • Simple modular expansion possible with future-orientated automation components
