APPLICATION
The 4-way directional control valves type IWE6…
electrically operated are intended for change in direction
of fluid flow in a hydraulic system. This valve is mainly
used in hazardous areas especially in underground pit
mines (group I) and in equipment working in vicinity of
flammable substances like gas, vapour, fog (group II). It
is certified with explosion proof attest - ATEX:

GOST - R: PO Ex ia I Ma;

IIC T5/T6 Gb. Can work
with outlet explosion proof circuit “ia” or “ib” with
maximum parameters Ui = 15 V;
V li = 1,6 A; Ci = 0;
0 Li = 0.
Temperature classes T5 and T6 are dependent on
ambient temeperature, according to data table on
page 2.
DESCRIPTION OF OPERATION
The directional valve is switched by changing position of
the spool (3) which moving along its axis separates or
connects ports A , B , P , T in the housing (1). The move of
the spool is secured by the putting voltage on coil (2)
through the terminal strip (10) The return of the spool is
realized by the spring (4). A n optional manual override
button (6) permits movement of the spool without
solenoid. The valve is equipped with explosion proof
solenoid type EMSGI – 45. Solenoid is assembled with
sleeve (5) and manual override button (6).
There is a coil (2) on the sleeve (6). Outside of coil
mounted is cable box (7). Inside the cable box (7) are
diodes as well as safety device (9) preventing excessive
current increase. Electrical connection for is realized by
using terminal strip (10) and for type with light signaling
applied diode LED (11). The diode is mounted inside cable
box (7). Power lead must be sealed and immobilized
using gland (12). Sealing rings (14) protect the coil against
external impacts and prevent from turn of coil after
tightening up the nut (13).

ASSEMBLY AND OPERATION REQUIREMENTS
1.
2.
3.
4.
5.
WK 499 775
Electric connection of the valve must be
made according to electric scheme on
page 5.
5.
Conductors of valve must be meet
requirements applied in the mining
machinery.
Only skilled workers can direct connect
valve to an
an electrical system.
The plug must be supported by retains
screw.
During the period of operation must be
kept the fluid viscosity and filtration
according to requirements defined in
Service Manual
02.2014
6.
In order to ensure the failure free and safe
operation must be check:
• condition
condition of the electrical connection
• the verity proper working of the valve
• cleanness of the hydraulic fluid
7. Any valve repair in the mine condition is
forbidden. A damaged valve must be
supplied to the producer in order to repair.
The address of service is shown on the last
page of this Data sheet – Service Manual
8. A person that operates the valve has to
acquaint with Service Manual.
