The Bosch Rexroth R900912910 is a type DBW pilot-operated pressure relief valve. It is engineered to limit the operating pressure within a hydraulic system and features a solenoid-actuated unloading function. This allows the system pressure to be unloaded to the tank when the solenoid is energized, providing remote control over pressure relief. The valve consists of a main valve with a main spool insert and a pilot control valve with a pressure adjustment element. Designed for subplate mounting, it adheres to the ISO 6264 porting pattern, ensuring easy integration and interchangeability in industrial hydraulic applications that demand reliable pressure limitation and switching capabilities.
