DB/DBW Pressure Control Valve is a pilot Relief Valve.
They are used to limit (DB) or limit and system pressure with solenoid (DBW). The relief valve (DB) mainly consists of main valve (1) with main spool insert (3) and pilot with pressure regulating element valve (2).
DB type relief valve
The pressure in circuit A acts on the main spool (3). At the same time, the pressure acts on the ball (8) of the main (3) and the first (2) through the belt joint (4) (5 system passage (6) (7). If the pressure in the passage A exceeds the spring (9) The setting value, ball (8) overcomes bullet (9) and opens.
The signal for this is supplied internally from the A channel by the control oil (10) and (6). The oil on the loading side of the main spool (3) passes through the control port (7), throttling (11) and ball (8) into (12). From here internal supply - DB-5X-type via control channel (13), or external supply - DB..-5X..Y-type, via control channel (14) into tank. Orifices (4) and (5) create a pressure drop across the spool (3), opening from the A-pipe to B-pipe connection. Oil flows from pipe A to pipe B, while the set working pressure remains unchanged. The relief valve can be unloaded or switched over to a different pressure (second pressure rating) via port X (15).
