Product Overview
The Rexroth DB 10 K2-4X/315YV is a direct-operated pressure relief valve from the proven DB series, designed for precise system pressure limitation and overload protection in industrial hydraulic circuits. Manufactured by Bosch Rexroth, this valve operates on a spring-loaded poppet principle: when system pressure exceeds the set value, the poppet lifts off its seat, diverting excess flow to the tank port and thereby maintaining the working pressure at a constant, pre-set level. The “315” designation indicates a pressure rating of up to 315 bar, making this valve suitable for high-pressure industrial applications. The “YV” suffix denotes a specific adjustment and connection variant within the DB 10 K2-4X family. As a pressure control valve, it serves as a critical safety and regulation element in hydraulic power units, ensuring that pumps, actuators, and downstream components are protected against pressure spikes and sustained overpressure conditions.
