The pressure sequence valve
DZM12131PE is a pilot-operated, spring-
loaded spool valve with a pilot drain at port
4. This means that pressures across port 3
have no inuence on the pressure setting.
If the pressure at port 1 exceeds the pre-
set spring tension, the pilot stage opens
and oil ows from behind the main piston
to tank port 4. The resulting pressure
differential causes the main piston to move
against the reset spring and allows oil to
ow from port 2 to port 3 or vice versa.
Up to 200 l/min
Up to 350 bar
