Pressure valve type DB is a pilot-operated pressure relief valve.
It is used for limiting the operating pressure.
The pressure relief valves (DB) basically consist of the main valve
(1) with main spool insert (3) and pilot control valve (2) with
pressure adjustment element.
The pressure applied to channel P acts on the main spool (3). At
the same time, pressure is applied to the spring-loaded side of the
main spool (3) and to the ball (8) in the pilot control valve (2)
via the control lines (6) and (7) which are equipped with nozzles
(4) and (5). If the pressure in channel P exceeds the value set at
the spring (9), the ball (8) opens against the spring (9). The
corresponding signal comes internally, via the control lines (10)
and (6) from channel P. The hydraulic fluid on the spring-loaded
side of main spool (3) now flows via the control line (7), nozzle
bore (11) and ball (8) into the spring chamber (12). From here, it
is fed into the tank, either internally for type DB …– via control
line (13), or externally for type DB…Y via control line (14).
Nozzles (4) and (5) cause a pressure drop to occur at the main
spool (3), hence the connection from channel P to channel T opens.
Now, the hydraulic fluid flows from channel P to channel T
maintaining the set operating pressure.
