DATA SHEET - OPERATION MANUAL

APPLICATION

Proportional directional valve type USEB10... is used to control
the direction and speed of movement of an actuator. Flow rate
of hydraulic oil directed to the actuator is adjusted by change of
electric current supplying the solenoid coil.

DESCRIPTION OF OPERATION

The proportional directional valve type USEB 10 sonsists of the housing
1, solenoids 2 and 4,inductive offset detector 3, spool 5, springs 6 and 7.
Electric regulator (30 RE ...) can be included with thevalve. The regulator is
applied to control proportionalsolenoids and receive the signals from offset
detector.The proportional solenoid 2 or 4 pushes the spool fromits neutral
position. The neutral position is held by thesprings 6 and 7. The inductive
offset detector hasdouble stroke. Its range allows to measure the offsetof
the spool from neutral position to the right or left.The offset of the spool

5 is transmitted electrically asinitial data. It is held in the signal sent by the
electronicregulator in form of current with certain intensity that ischanged
by the solenoid 2 or 4 into force pushing thespool 5 against spring 6 or 7.
Simultaneously the offsetdetector 3 determines actual position of the
spool and inform of electrical signals sends as feedback to theelectronic
regulator. The both signals: initial data andactual value are compared in
the electronic regulator,which sends a new signal correcting the position of
thespool 5 in order to adjust it in conforming with the initialsignal
