The Bosch Rexroth DBAR40F2-1X/50/12 (R900550277) is a high-quality pump safety block designed to be directly mounted onto the SAE pressure port of pumps. This pilot-operated pressure relief valve is integral for limiting the operating pressure within hydraulic systems. The DBAR40F2-1X/50/12 consists of a valve block, a main spool insert, and a pilot control valve, which work together to maintain system integrity and safety. The device features a P port for hydraulic fluid input and an additional P port for output. It operates by allowing the applied pressure in the throughbore to act on the main spool while also applying pressure to the spring-loaded side of the main spool and to the ball in the pilot control valve through nozzles. When the set pressure is exceeded, the ball opens against its spring, causing fluid to flow into the tank either internally or externally depending on the type of DBA. This model includes an integrated check valve that maintains system pressure when disconnected from the pump, eliminating the need for a separate check valve. It ensures zero-pressure startup and quick circulation of the pump for efficient operation. Users can adjust pressures quickly and accurately using various adjustment types such as rotary knobs or sleeves with hexagons, some featuring scales or protective caps. Additionally, this pump safety block allows for solenoid-actuated unloading via a built-on directional valve. It also provides options for remote control purposes through port T, ensuring versatility in application. The Bosch Rexroth DBAR40F2-1X/50/12 offers reliability and precision in controlling hydraulic pressures within complex systems.
