Product Overview
The Rexroth LC40A20E70 (Material No. R900938000) is a high-performance 2-way cartridge valve engineered by Bosch Rexroth for demanding industrial hydraulic systems. Operating on a two-stage, pressure-compensated poppet principle, this cartridge valve functions as a pilot-operated logic element that controls flow direction and pressure within a manifold block. The LC40A20E70 is designed for installation into a standardized receiving bore, where it serves as a compact, high-flow directional control element. With a nominal size of NG40 and an area ratio of 20:1, this valve delivers reliable bidirectional flow control and leak-free sealing, making it an essential component in modern high-pressure hydraulic circuits.
