Construction
The GEMU 675 manually operated 2/2 way metal diaphragm valve has a non-rising handwheel and an integral optical position indicator as standard.

Features
  • Suitable for inert and corrosive liquid and gaseous media
  • Insensitive to particulate media
  • Valve body and diaphragm available in various materials and design
  • Various connection available
  • Compact design (when space is at a premium)
Advantages
  • Optional flow direction, will seal in either flow direction up to full operating pressure
  • Optional mounting pressure
  • Due to its modular design, stocks of valve spares are minimized

Working Medium

Working Medium Corrosive, inert, gaseous and liquid media which have no negative impact on the physical and chemical properties of the body and diaphragm material.
Max. Perm. Temperature of Working Medium 150 ºC
  • 1 The combination of PFA or PTFE lining with 5E diaphragms is only conditionally suitable for gaseous media. If low seat leakage rates are required for gaseous media, other combinations are preferable.
