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
