Ident. code: I (piston spool valve)
Function:
1)
–
Two monostable 2/2-directional control
valves, both valves normally closed,
reversible valve on control side 14
–
Pneumatic spring return
With dual-pressure operation:
–
Supply operating pressure via port 1
–
Operating pressure can be separately
supplied at port (3/5).
–
With solenoid coil 14, operating pressure is
switched from port (5) to port (4).
–
With solenoid coil 12, operating pressure is
switched from port (1) to port (2)
With vacuum operation:
–
Supply operating pressure via port (1)
–
Supply vacuum via port (5).
–
With solenoid coil 14, vacuum is switched to
port (4).
–
Plan a filter at port (4) or in tubing 4 so that
no contamination can enter the valve.
–
With solenoid coil 12, operating pressure is
switched to port (2) (e.g. for an ejector pulse
in vacuum operation).
–
For an ejector pulse, establish a connection
using a T-piece between ports (2), (4) and the
suction cup complete.

Note: If this 2/2-directional control valve (ident. code I) is also operated with other valves on the MPA-S valve terminal, this 2/2-dir-
ectional control valve must be operated in a separate pressure zone with a separated exhaust duct (5).
