Product Overview
The Rexroth LC40A10E70 (Material Number: R900937998) 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 pilot-operated, seat-type directional control element designed for installation into a standardized receiving bore. The LC40A10E70 features a size 40 mounting pattern and an area ratio of 10:1 (A1:A2), enabling efficient pressure intensification and reliable sealing in high-pressure circuits. When combined with a suitable pilot control valve, it serves as a main stage directional spool element for controlling flow direction, pressure, and load holding in complex hydraulic manifolds. Its robust design ensures minimal leakage, fast response, and long service life in continuous industrial operation.

Engineering Features & Advantages
- Precision Performance: The 10:1 area ratio provides high opening forces with low pilot pressure, ensuring fast and reliable spool actuation for precise directional control.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened and ground spool and seat for wear resistance and minimal internal leakage.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth LC series cartridge valves, allowing drop-in replacement without manifold modification.
- Compact Manifold Design: Cartridge construction reduces system size and piping, enabling high flow capacity in a compact installation envelope.
- Versatile Integration: Compatible with a wide range of Rexroth pilot control valves for customized pressure, directional, or load-holding functions.
Typical Industrial Applications
This 2-way cartridge valve is widely used in heavy industrial hydraulic systems such as plastic injection molding machines, metallurgical presses, construction and marine hydraulics, CNC machine tools, and general hydraulic power units requiring reliable directional control, pressure holding, and fast switching of large flows. It is also suitable for manifold-based systems in steel mills, offshore equipment, and automated production lines where leak-free performance and high cycle rates are critical.
