Ident. code: I (pisto n spool valve)
Function:
1)
– Two monostable 2/2-directional control
valves, both valves normally closed,
reversible v alve on control side 14
– Pneumatic spring return
With dual-pressure operation:
– Supply operating pressure via port 1
– Operating pre ssure can be separately
supplied at port (3/5).
– With solenoid coil 14, operating pressure is
switched from port (5) t o 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.
1) 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).
