Product Description

1. Product Description
Pressure relief valve, pilot operated, types DB/DBW. .. L5XThe 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). If the pressure in channel A rises excess the setting value at the spring (9), the 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 DB···L5X···Y, oil flows via control line (14) into the tank. In virtue of the orifice (4) and (5), the pressure drop arises at the main spool (3), and 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).
Pressure relief valve type DBW
The basis function of pressure relief valve type DBW is the same with pressure relief valve type DB, the difference is that valve type DBW operates unloading via a built-on directional valve (16).
