Product Overview
The Rexroth LC40B05E70 (Material Number R900938002) is a high-performance 2-way cartridge valve engineered for demanding industrial hydraulic systems. As part of the Rexroth LC series, this logic cartridge valve functions as a pressure and directional control element, designed to be installed into a standardized receiving cavity within a manifold block. The LC40B05E70 features a size 40 mounting pattern and utilizes a poppet-type seating design that ensures zero-leakage sealing when closed. This valve is actuated by a separate control cover (not included) which can be configured for pilot pressure, solenoid, or manual operation, making it a versatile building block for complex hydraulic circuits. Its robust construction and precise metering characteristics make it ideal for high-flow, high-pressure applications where reliable switching and load-holding capabilities are critical.
