Product Overview
The Rexroth DB 10-1-52/315 is a direct-operated pressure relief valve engineered for precise system pressure limitation and protection in industrial hydraulic circuits. As part of the renowned Rexroth DB series, this valve operates on a proven poppet-and-spring principle, where a pre-set spring force acts against the hydraulic pressure on the valve poppet. When system pressure exceeds the adjusted set value, the poppet lifts off its seat, diverting excess flow to the tank port and thereby safeguarding downstream components from overpressure damage. With a nominal pressure rating of 315 bar, the DB 10-1-52/315 is designed for demanding high-pressure applications requiring reliable, repeatable pressure control. Its robust construction and precision-machined internal components ensure stable operation, minimal pressure override, and long service life in continuous industrial duty.
