VAN MANG GEMU MODEL 671

Construction

The GEMU 611 and GEMU 671 manually operated 2/2-way metal diaphragm valves have a low maintenance plastic bonnet and an integral optical position indicator as standard.

Features

  • Suitable for inert and corrosive liquid and gaseous media
  • Chemical resistance of bonnet
  • Insensitive to particulate media
  • Valve body and diaphragm available in various materials and designs
  • Compact design (ideal when space is at a premium)

Advantages

    • Hermetic separation between medium and bonnet
    • Optional flow direction
