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

ISO 4401 SIZE 03

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
