The DBW20BG2-5X/315S6EG24N9K4R12V valve belongs to the DB Pressure Relief Valves series and is produced by Bosch Rexroth for controlling pressure in hydraulic automation circuits. The nominal size is 25, giving flow passages that handle up to 500 l/min without excessive velocity. A set pressure of 315 bar defines the point at which the relief stage opens, while ports P and x are rated for a maximum of 350 bar and ports Y and t withstand 210 bar. The valve is normally open so flow passes until the solenoid pilots it closed, and switching shock damping is included to limit pressure spikes during each change of state. An integrated directional valve is supplied, combining relief and directional functions in one assembly to reduce manifold complexity.
Solenoid operation is powered by a 24 V DC coil, and a three-pole connector (2 + PE) provides the electrical interface for quick wiring. A concealed manual override lets technicians shift the spool during commissioning without exposing moving parts. Pressure adjustment is carried out through a sleeve fitted with a hexagon and cap, allowing sealed setting changes with a standard wrench. Threaded process ports fulfill the specified threaded connection type and simplify line mounting. FKM seals resist common hydraulic fluids at elevated temperatures, and the uniform threaded connection at every port maintains consistent assembly torque across the installation.
