Product Overview
The DB10K1-45/315 YV is a pilot-operated pressure relief valve engineered for precise system pressure regulation and overload protection in industrial hydraulic circuits. Operating on a balanced piston pilot stage principle, this valve maintains stable pressure control by diverting excess flow to tank once the preset cracking pressure is reached. The “315” designation indicates a nominal pressure rating of 315 bar, making it suitable for high-pressure industrial applications. The YV suffix denotes a specific adjustment and sealing configuration, typically featuring a protected adjustment screw and optional vent port for remote pilot control. This valve serves as a critical safety and control element in hydraulic power units, ensuring system pressure does not exceed safe operating limits while providing smooth, low-hysteresis response to pressure fluctuations.
