Ident. code: I, function:
1)
– Two monostable 2/2-way 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 connec­
tion using a T-piece between ports (2), (4)
and the suction cup
1) Note: If this 2/2-way valve (ident. code I) is connected to other valves on the valve terminal, the 2/2-way valve is operated in
a separate pressure zone with separate exhaust duct (5).
