Direct-Operated Servo-Proportional Valves for Analog Signals D936 and D937 Series

D936 and D936 Servo-Proportional Valves


  • Directly driven by a proportional solenoid
  • 4/4-way design including failsafe position reduces need for additional safety components
  • Fully hardened spool and bushing provides 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
  • Optimized overlaps and clearances between spool and bushing deliver low internal leakage and high contamination resistance
  • Electronics placed on the solenoid delivers compact design for minimum installation space
