MULTIPOL-IP65
PRESSURE SUPPLY OF PILOT VALVES
A MEGA spool valve is equipped on one side with a spacer sealing which also provides for a
selecting function:
- The spool valve can be adapted to either internal or external pilot pressure supply simply by
rotating this sealing.
- The position selected for each spool valve can be identified from the outside even after the spool
valves have been assembled to islands.
- Internal and external pressure supply can be mixed on one island.
- If the components are supplied separately, the spool valves are delivered with the sealing placed
in INT for internal pressure supply.
■ Internal pressure supply to pilot valves
Identification underneath the spool valve
In this configuration:
The pilot valves are directly supplied with pressure by using the
supply pressure (1) in the middle of the spool valve.
The common pressure supply (spool valve and pilot valves) is
3 to 8 bar (2 to 8 bar with bistable 5/2 spool valves).

■ External pressure supply to pilot valves
Identification underneath the spool valve
In this configuration:
- The spool valves on an island can be supplied with low pressure
and vacuum.
- The pilots and the spool valves on an island can be supplied with
pressure over 2 separate lines.
Supply pressure of pilot valves: 3 to 8 bar
(2 to 8 bar with bistable 5/2 spool valves)
Supply pressure of spool valves: -0.950 bar to +8 bar.
Connection of pilot pressure supply 12/14 at either one of the 2 end
covers.
