  • Features

The pneumatically operated GEMÜ D41 diaphragm valve is designed for use in sterile applications.The diaphragm hermetically separates the actuator from the working medium. The GEMÜ D41 valve with EasyLock technology is installed entirely without loose components using a central gearbox. All actuator parts (except the seals and design elements) are made from stainless steel. The "Normally closed", "Normally open" and "Double acting" control functions are available. The valve has an optical position indicator with a transparent cap as standard.

  • 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 thanks to the flow-optimized valve body
  • Identification of the mounting angle (hash mark)
  • Optical position indicator and transparent cap as standard
  • Simple modular expansion possible thanks to state-of-the-art automation components
