Product Overview
The Rexroth LC 16 A20E7X (Rexroth part number R900910269) is a two-stage logic cartridge valve designed for high-pressure, high-flow hydraulic control in industrial power units. As a cartridge-style directional control element, it functions as a pilot-operated seat valve that opens or closes the main flow path in response to a pilot pressure signal applied at the control cover. The LC series is engineered for installation into a standardized receiving cavity, allowing compact manifold integration without the need for separate subplate piping. This valve is widely used as a main stage switching element in systems requiring fast response, leak-free sealing in the closed position, and reliable operation under continuous industrial duty.

Engineering Features & Advantages
- Precision Performance: Pilot-operated seat design delivers fast, defined switching with minimal internal leakage in the closed position, ensuring accurate directional control of main hydraulic flow.
- High Flow Capacity: The NG16 cartridge format accommodates substantial flow rates within a compact manifold footprint, reducing overall system size and piping complexity.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened sealing surfaces and robust construction for long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, including the R900910269 part number, ensuring drop-in replacement without modification.
Typical Industrial Applications
This logic cartridge valve is commonly deployed in plastic injection molding machines, metallurgical presses, hydraulic power units for construction and marine equipment, and CNC machine tool hydraulic circuits. It is particularly suited to manifold-based systems where compact directional control, high pressure capability, and reliable seat sealing are required for main stage switching functions.
