Construction
The GEMU 205 directly controlled 2/2-way plastic solenoid valve has a high performance coil which is hermetically separated from the medium by means of a flexible PTFE bush. The valve seal is carried in a pendulum bearing. The electrical connection is made via a plug complying with DIN EN 175301-803 form A. The DC design includes a rectifier in the terminal enclosure, so that the valve can be used with an AC supply. The valve has a manual override and an optical position indicator as standard.

Features
  • Suitable for inert and corrosive liquids and gases
  • Corrosion-resistant, therefore suitable for water treatment plants, washing and cleaning installations, the food and foodstuffs industries, the chemical industry, electroplating, titration equipment, for the photographic industry and for laboratory, analytical and medical apparatus.
Advantages
  • Hermetic separation of medium and actuator
  • Damped action on closure
  • Manual override allows the valve to be opened and closed during a power failure
  • Optical position indicator
