Product Overview
The Rexroth DB 10-1-52/315 (Material Number: R900598998) is a direct-operated pressure relief valve engineered for precise system pressure limitation and protection in industrial hydraulic circuits. Manufactured by Bosch Rexroth, a global benchmark in hydraulic component design, this valve operates on a spring-loaded poppet principle: system pressure acts on the valve poppet, and when the preset cracking pressure is exceeded, the poppet lifts off its seat to divert excess flow to the tank port, thereby capping the circuit at the adjusted pressure level. The “315” designation indicates a nominal pressure setting of 315 bar, making this valve suitable for high-pressure industrial power units, test stands, and demanding machine tool circuits. Its compact DB 10 size (NG10 / CETOP 5 interface) allows direct inline or manifold mounting, and the adjustable spring pre-tension provides stepless pressure setting across the valve’s rated range. As a pressure control valve, it serves as the primary safety and pressure-regulating element in hydraulic power packs, ensuring downstream components are shielded from overpressure events and that system pressure remains stable under varying load conditions.

Engineering Features & Advantages
- Precision Pressure Limiting: The direct-operated poppet design delivers fast, repeatable response to pressure spikes, protecting pumps, cylinders, and downstream valves from overpressure damage with minimal hysteresis.
- High-Pressure Capability: Rated for a 315 bar pressure setting, this valve is suited to high-pressure industrial circuits where standard low-pressure relief valves would be inadequate.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened internal components and a robust housing that resists wear and contamination-induced failure.
- Stepless Adjustment: The spring-loaded adjustment mechanism allows precise, infinitely variable pressure setting to match specific circuit requirements without the need for component replacement.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, ensuring drop-in replacement for existing Rexroth DB 10 series installations.
