Bosch Rexroth AGA-1855-2 Hydraulic Cartridge Relief Valve Manifold

Bosch Rexroth AGA-1855-2 Hydraulic Cartridge Relief Valve Manifold is a compact block that houses a Rexroth cartridge relief valve in a single manifold to deliver overpressure protection for hydraulic circuits while simplifying install and maintenance. Designed for modular relief control, the AGA-1855-2 accepts standard Rexroth cartridge relief valves and routes relief flow within the manifold structure, enabling centralized protection in compact hydraulic assemblies. The designation appears in Bosch Rexroth manifold catalogs and, in some distributor listings, as AGA-1855-2-C, indicating variants or region-specific part numbering. Typical applications include industrial hydraulic systems in machine tools, presses, plastics equipment, and other automation cells where space is tight and a precise relief function is required. This manifold assembly supports a cartridge-type relief valve configuration, offering a straightforward path to configure and service relief settings without mounting separate valves, and it aligns with Rexroth’s standard manifold and cartridge architectures for consistent installation and interchangeability. For exact specifications—such as relief-set ranges, cavity compatibility, porting details, mounting pattern, and material grade—consult the Bosch Rexroth RA09907 manifold catalog or reach out to a Rexroth distributor to confirm the specific AGA-1855-2 configuration and any regional variant.
