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
