Function, section
In the initial position the valves are closed. The pressure in
channel A acts on the spool (1). At the same time,
pressure is applied to the spring-loaded side of the
spool (1) via nozzle (2) and to the pilot poppet (6) via
nozzle (3). If the pressure in channel A exceeds the value
set at the spring (5), the pilot poppet (6) opens. Hydraulic
fluid flows from the spring-loaded side of the spool (1),
nozzle (3) and channel (8) into channel T (TA). The
resulting pressure drop moves the spool (1) and opens the
connection from A to T (TA). In channel A, the pressure set
at the spring (5) settles.
Pressure valves of type ZDB and Z2DB are pilot-operated
pressure relief valves in sandwich plate design. They are
used for limiting a system pressure.
The valves basically consist of the housing (7) and one or
two pressure valve cartridges. The system pressure can be
set via the adjustment type (4).
