This valve may be used either normally open or normally closed.
Normally closed: pressure inlet port 1 (P).
Normally open: pressure inlet port 3 (R).
A signal arriving at 12 (Z) switches the flow of the valve from 1 (P) to 2 (A) and closes port 3 (R) after the set time
has expired.
Instead of supplying main pressure to either port 1 or 3, the branched signal line can be connected to 1 or 3.
The signal line to port 1 or 3 must not be longer than the signal line to port 12.
