Solenoid valves, servo-assisted, with 3/2-way pilot

A pivoted-armature or rocker valve with isolating diaphragm is used as the pilot valve. The essential difference with respect to the 2-way pilot is that a medium does not flow through the pilot in an open switch position and thus there is a much slighter risk of clogged control bores due to dirty media. In addition, a diaphragm protects the solenoid armature against harmful influences. The chief field of application of this functional principle (e.g.: Type 142 and Type 5282) therefore obviously relates to both dirty media and aggressive media.

Advantages:

  • No small control bores in the diaphragm and thus less sensitive to dirty media
  • Solenoid chamber protected by isolating diaphragm
  • Only a small quantity of medium flows through the pilot valve for opening or closing
  • No medium flow through the pilot valve in open condition! This is a crucial advantage over valves with 2-way pilot.
  • Response times adjustable with adjusting screws
  • NC and NO function, possible simply by turning the pilot
  • Extremely high functional reliability
  • Also available as explosion-proof version.
