Description

OEM-quality Rexroth solenoid valve R901155051 engineered for replacement in Rexroth main control valve assemblies. This solenoid valve controls hydraulic flow direction in proportional and on/off hydraulic circuits, making it essential for excavator implement functions including boom swing, arm regeneration, and bucket curl. The R901155051 features precision-manufactured valve internals with surface-hardened components that resist wear from contaminated hydraulic fluid, extending service life in harsh operating conditions. The electromagnetic solenoid assembly utilizes high-grade copper windings with epoxy encapsulation to prevent moisture ingress and vibration damage. Compatible with Rexroth’s standard electrical connector configurations, simplifying installation and wiring connections. The R901155051 is widely used across multiple Rexroth valve series and is commonly found in excavators from brands including Caterpillar, Liebherr, and other manufacturers that specify Rexroth hydraulic components.
