Construction

The GEMU 698 motorized 2/2-way diaphragm valve has a low maintenance electric actuator with a toothed belt drive and a reversible synchronous motor. A manual override and an optical position indicator are standard.

Features
  • Suitable for inert and corrosive liquid and gaseous media
  • Chemical resistance of actuator
  • Stainless steel body with CIP/SIP cleaning and sterilizing capabilities
  • Insensitive to particulate media
  • Valve body and diaphragm available in various materials and designs
  • The valve stroke can be limited by means of adjustable limit switches
  • Suitable for use as a control valve (with GEMU 1283)
Advantages
  • Hermetic separation between medium and actuator
  • Optional flow direction, will seal in either flow direction up to full operating pressure
  • Optional mounting position
  • Consistent control system and reliable opening and closing action
  • Direct 0/4 - 20 mA signal processing using the additional module GEMU 1283
  • Electrical position feedback by means of a potentiometer available as an option
