DESCRIPTION APPLICATION
Direct operated proportional spool valve with 4 connections in Proportional spool valves are perfectly suitable for demanding
5-chamber system with integrated electronics. The Plug & Play tasks due to the high resolution, large volume flow and low hystere-
valves are factory set and adjusted and have therefore a high sis. The applications are in the industry as well as in the mobile
valve-to-valve reproducibility. With protection class IP67 for the hydraulics for the smooth control of hydraulic actuators. Some
electronics, these valves are suitable for harsh environmental examples: control of the rotor blades of wind generators, forestry
conditions. Proportional to the electronically transmitted and earth moving machines, machine tools and paper production

interface or a fieldbus interface (CANopen, J1939 or Profibus DP). Note! „PASO” is a Windows programm in the flow diagram
The parameterisation takes place by means of the free of cost para - style, which enables the intuitive adjustment and storing
of all variable parameters. The data remain saved in
meterisation and diagnostics software «PASO» or via fieldbus case of a power failure and can also be reproduced and

through a screw plug. As an option, these valves are available with
integrated controller. As feedback value generators sensors with
voltage or current output can be connected directly. The available
controller structures are optimised for applications with hydraulic
actuations.
