Technical Data Hydraulic Data

Compact, electrohydraulic 4/3-way proportional valve with linear flow characteristic curve and position feedback of piston. The single-stage design in size 6 with a strong proportional linear motor as well as the digital onboard digital elec-tronics is ideal for demanding hydraulic control tasks.

Excellent dynamic and static characteristics are achieved by the newly-developed linear motor in connection with the digital electronics of the integrated position control loop. A good resolu-tion is reached by the high power reserve of the linear motor even with lower oil-purity classes. The proven, low leakage single-stage construction method guarantees maximum energy efficiency.

Through a protected USB interface the servo control valve is custom configured with a standard PC or laptop. The digital electronics allows an optimum setting to be transferred to other systems.
