Cartridge Seat Valve series WS22G / OD

Pressure [bar]


Flow rate [L/min]


These direct acting 2/2 solenoid operated directional seat valves, series WS22GD… / WS22OD…, are screw­in cartridges with a M20x1.5 or 3/4­16 UNF mounting thread. They are designed on the poppet/seat principle, and are therefore virtually leak­free in both directions of flow (bidirectional seat­valve shut­off). Over­excitation, preferably through an electronic switching device (booster), is required to operate the solenoid. Combined with the low mass of the moving parts, this results in short response times and high switching performance in a compact package. “De­energised closed” and “de­energised open” functions are available. The straightforward design delivers an outstanding price/performance ratio. The valves are used in applications in digital hydraulics, where fast response and long life with minimum size are vitally important.

  • For use in digital hydraulics
  • With bidirectional seat-valve shut-off
  • Compact construction for cavity type ALM – M20x1.5
  • High switching performance
  • Short response times
  • All exposed parts with zinc-nickel plating
