DBDS10G1X/400/12

The DBDS10G1X/400/12 is manufactured by Bosch Rexroth for the DB Pressure Relief Valves series. Designed to stabilize hydraulic automation circuits, the valve opens when system pressure exceeds a preset level to safeguard pumps and actuators. Its nominal size of 10 defines the flow cross-section and fits medium-capacity subplates. A maximum inlet pressure of 400 bar allows reliable operation in high-pressure installations, while a maximum flow of 120 l/min accommodates moderate volume demands without excessive loss. The adjustment uses an S-style hexagon with a protective cap so technicians can set pressure precisely and lock the screw against disturbance. Threaded ports in the G pattern simplify direct mounting to manifold blocks, and NBR sealing material resists standard mineral hydraulic oils.

Downstream pressure is limited to 315 bar, keeping return lines within safe limits for hoses and reservoirs. The body carries an overall pressure rating of 400 bar to endure full load cycles without structural fatigue. A SAE Code 12 line connection unifies the external piping interface for equipment built to common North American standards. Port P is threaded 3/4-16 UNF to admit the supply stream, and port T is threaded 9/16-18 UNF for controlled discharge to tank. A 7/16-20 UNF measuring port permits gauge or transducer attachment when diagnostic readings are required. These port arrangements, combined with the specified adjustment hardware, allow the unit to be integrated quickly into new or existing hydraulic assemblies.
