The Bosch Rexroth DBC 2-5X/315V SO515 (R900513438) is a high-performance pressure relief valve designed for efficient control of operating pressure in hydraulic systems. This pilot-operated valve is integral for limiting the system pressure to safeguard against overpressure conditions which could potentially damage equipment or disrupt system operation. The DBC 2-5X/315V SO515 comprises a main valve with a main spool insert and a pilot control valve that includes a pressure adjustment element, ensuring precise pressure regulation. The working principle of this valve involves the applied pressure in channel P acting upon the main spool while also being directed to the pilot control valve through control lines equipped with nozzles. Upon reaching the set value, the ball within the pilot control valve overrides the spring tension, allowing hydraulic fluid to flow into the tank, thus maintaining desired operating pressure. This model offers versatility through its unloading capability and option to switch to an alternative second pressure rating via port X. It is designed for subplate mounting with porting patterns compliant with ISO standards NG6, NG10, and NG16. Additionally, it can be utilized as a screw-in cartridge valve for threaded connections. The DBC 2-5X/315V SO515 comes with various adjustment types for precise pressure settings including a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale. These options provide flexibility for different operational requirements and user preferences. Moreover, this model features a corrosion-protected design which enhances its durability and longevity in harsh working environments. The versatility of mounting options and adjustment types makes this Bosch Rexroth model suitable for a wide range of applications demanding reliable pressure regulation in hydraulic systems.
