DESCRIPTION APPLICATION
Direct operated proportional spool valve with 4 connections in Proportional spool valves are perfectly suitable for demanding
5-chamber system. Precise spool fit, low leakage, long service life tasks due to the high resolution, large volume flow and low hyste-
time. The volume flow adjustment takes place by a Wandfluh resis. The applications are in the industry as well as in the mobile
proportional solenoid. Proportional to the solenoid current, the hydraulics for the smooth control of hydraulic actuators. Some
spool stroke, the spool opening and the valve volume flow increase. examples: control of the rotor blades of wind generators, forestry
For the control, Wandfluh proportional amplifiers are available (see and earth moving machines, machine tools and paper production

register 1.13). machines, simple position controls, robotics and fan control.
