Product Overview
The Rexroth DB 10-2-52/315 (Material Number: R900590334) is a direct-operated pressure relief valve engineered for precise system pressure limitation and overload protection in industrial hydraulic circuits. As a member of the proven DB series, this valve operates on a spring-loaded poppet principle, where a balanced piston and adjustable compression spring establish the cracking pressure. When system pressure exceeds the set value, the poppet lifts off its seat, diverting excess flow to the tank port and thereby safeguarding downstream components from pressure spikes. The DB 10-2-52/315 is a screw-in cartridge style valve with a nominal size of NG10 (Size 10), designed for subplate mounting or manifold installation. Its robust construction and precise pressure adjustment make it a critical safety and control element in demanding hydraulic power units, presses, and injection molding machines.
