Servo valves and proportional valves
D936 / D937
D936 and D937 valves move the spool directly using a proportional solenoid, with integrated electronics and position control. They control flow in electrohydraulic systems and integrate into motion, speed, force and pressure control loops.
01Direct operation without pilot oil
024/4 design with Fail-safe position according to order code
03Analog command interface and electronics with a digital core
04Hardened spool and sleeve; electronics mechanically isolated from valve body
The model will be added to your request. The B.N. team will check its suitability for your operating conditions.
