Product Overview
The Rexroth DBDH15G1A/25 (Material No. R900432893) is a direct operated pressure relief valve from the proven DBDH series, engineered to protect hydraulic systems against excessive pressure and to serve as a reliable pressure-limiting control element. As a direct operated poppet-type valve, the pressure setting is achieved through a mechanically adjustable spring that acts directly on the valve poppet, providing fast response and stable pressure regulation without pilot-stage dependency. The valve is designed for inline mounting and is widely deployed in industrial power units, test stands, and machine tool circuits where precise, repeatable cracking pressure and dependable overpressure protection are essential. Its robust housing and hardened internal components make it suitable for continuous duty in demanding hydraulic environments.
