Construction
These directly controlled 2/2-way solenoid valves have a completely plastic encapsulated DC solenoid which drives the armature. The displacement of the armature takes place within a bellows made of PTFE backed by a safety diaphragm which provides additional sealing protection. The valve seat is directly mounted to the PTFE bellows. The valve body can be supplied either for straight through flow or with inlet and outlet at right angles. The electrical connection is made via a plug complying with DIN EN 175301-803 Form A. It has a rectifier for use with an AC supply.

Features
  • Suitable for inert and corrosive liquid and gaseous media
  • 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 photo graphic industry and for laboratory, analytical and medical apparatus.
Advantages
  • Easy to clean; the valve can be dismantled without tools by unscrewing the union nut
  • The solenoid can be replaced without removing the valve body from the pipeline
  • Hermetic separation between medium and actuator
  • UL approval available

Note

N/A Installation note:
Caution: DC solenoids are designed for unsmoothed voltages, e.g. as obtained from a bridge rectifier.

Wiring note:
Special wiring on request. When using electronic switches and additional wiring avoid inadmissible residual currents by proper design.
