Reliable manual valve with chambered diaphragm and sealed handwheel for 3-A® applications

Product information

The manually operated GEMÜ D20 diaphragm valve is designed for use in sterile applications. The diaphragm hermetically seals the actuator off from the working medium. Thanks to its sealed handwheel, the GEMÜ D20 is particularly suitable for 3-A®applications. All actuator parts (with the exception of the sealing and design elements) are made of stainless steel.

Key features

  • Sealed handwheel for 3-A®applications
  • Low-maintenance due to the firmly chambered diaphragm
  • Scaled visual display
  • Very high Kv values due to flow-optimised valve body
  • Suitable for use in hygienic and aseptic applications (CIP/SIP capable and autoclavable)
