Direct-Operated Proportional Valves for Analog Signals D926 and D927 Series

ISO 4401 SIZE 03 AND SIZE 05


  • Directly driven by two proportional solenoids
  • 4/3-way design including failsafe position reduces need for additional safety components
  • Spool-in-body design built for high accuracy and wear resistance
  • Electronics mechanically uncoupled from housing allows for high vibration resistance for longer service life and less machine downtime
  • Next-generation electronics with digital core and energy efficient components lead to low thermal stress and long electronics lifecycle
  • Large variety of spool overlap, flow characteristics, and signal options to fit numerous applications
  • Electronics placed on the solenoid delivers compact design for minimum installation space
