The proportional directional valve consists of a cast-iron
housing, a special control spool, two centering springs with
supporting washers and one or two proportional solenoids.
A control box, which comprises one or two electronic
control cards, depending on the number of the controlled
solenoids, can be mounted onto either solenoid. With the
model with two solenoids, the solenoid mounted apposite
the control box is connected with the box by means of a DIN
connector, a two-cored cable and a bushing. The
connection of the control box with the supply source and
with the control signal is realized by means of a 4-pin
connector, type M12 x 1. The solenoid coils, including the
control box, can be turned in the range of ± 90
o
.
The electric control unit supplies the solenoid with current,
which varies with the control signal. The solenoid shifts the
control spool to the required position, proportional to the
control current.
The electronic control unit provides the following
adjustment possibilities: Offset, Gain, rise and drop-out time
of the ramp generator, frequency (2 frequencies) and
amplitude of the dither signal generator. The correct
function of the control unit is signaled by LED-diodes.
Stabilized voltage +10V (+5V for voltage 12V) is also
available for the user. By the use of this voltage, a voltage
control signal can be made by means of a potentiometer
³ 1 kW.
The electronic control card enables voltage or current
control to be used, according to the positions of the
switches SW1 to SW3 (see table on page 6).
The basic surface treatment of the valve housing is
phosphate coated, the operating solenoids are zinc coated.
