– With dual-pressure operation:
– Supply operating pressure via port 1
– At port (3/5) separate o p erating pressure
can be supplied.
– With valve coil 14 operating pressure
is switched from port (5) to port (4)
– With valve coil 12 operating pressure
is switched from port (1) to port (2)
– With vacuum operation:
– Feed operating pressure via port ( 1)
– Feed vacuum via por t (5)
– With solenoid c oil 14, vac uum is switched

– At port (4) or in line 4, a filter is intended
so that no dirt can enter the valve.
