The types DB and DBW pressure valves are pilot operated pressure relief valves, used to limit

(DB) or limit and unload (DBW) the pressure via solenoid operating. The pressure relief valves

consist mainly of main valve (1) with main spool cartridge (3) and pilot operated valve (2) with

pressure adjustment elements.

Type DB pressure relief valves

The pressure of channel A acts on the main spool (3), meanwhile, pressure is applied via control

line (6) and (7) with orifice (4) and (5) on the spring loaded side of the main spool (3) and on the

ball (8) in the pilot operated valve(2).I f the pressure in channel A rises excess the setting value at

the spring (9),t he ball (8) opens against the spring (9). As for the internal control forms, signal is

given by control oil (10) and (6) supplied by channel A. The oil from the spring loaded side of the

main spool (3), via control line (7), orifice(11), and ball (8), then flows into spring chamber (12).

About internal drain - type DBL5XY, oil flows via control line(14) into the tank. In virtue of the

orifice (4) and (5),th e pressure drop arises at the main spool (3),a nd the connection from port A to

port B is open while the setting operation pressure maintain invariable. The pressure relief valve

may unload or shift the different pressure (second rated pressure value) in virtue of external

control port X (15).
