Pressure valve type DB is a pilot-operated pressure relief valve. It is used for limiting (DB) a system pressure.

The pressure relief valves basically consist of the pilot control valve (1) with pressure adjustment element (2), main valve (3) with main spool insert (4) and directional valve (5), optional.

Pressure relief valves type DB

The pressure applied by the system acts on the main spool (4). At the same time, pressure is applied to the spring-loaded side of the main spool (4) and to the pilot control valve (1) via the control lines (6) which are equipped with nozzles. If the system pressure exceeds the value set at the spring (7), the poppet (10) of the pilot control valve opens. The hydraulic fluid on the spring-loaded side of main spool (4) now flows via the spring chamber of the pilot control valve (1) to the tank, either internally via port T, or externally, via port Y. Due to the nozzle combination in the control lines, a pressure drop results at the main spool, the connection from P to T is thus released. The hydraulic fluid flows from channel P to channel T maintaining the set operating pressure.

The pressure relief valve can be unloaded by means of remote control or switched to another pressure value via port X (8).

Influencing of the switch-off time

The nozzle (9), by default equipped with Ø0.8 mm, is used to influence the switch-off time. By exchanging this nozzle (9), the switch-off time can be set to a slower or faster value.

The pressure limiting function is thus not influenced.
