Pneumatic 2/2-way diaphragm valve made of metal

GEMÜ D40

ConfigureTechnical data sheet
Stainless steel diaphragm valve with pneumatic actuator and hygienic design for the food and pharmaceutical industries.

Powerful diaphragm valve with encapsulated diaphragm

Product information

The pneumatically operated diaphragm valve GEMÜ D40 is designed for use in sterile applications. The diaphragm hermetically separates the actuator from the working medium. 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.

Key features

  • Low-maintenance due to the firmly chambered diaphragm
  • Fast, safe and simple diaphragm and actuator mounting
  • Very high Kv values due to flow-optimised valve body
  • Valve can be configured for the respective process parameters
  • Identification of the angle of rotation (hash mark), optical position indicator and transparent cap as standard
  • Simple modular expansion possible with future-orientated automation components
  • Suitable for use in hygienic and aseptic applications (CIP/SIP capable and autoclavable)
