Product Overview
The Rexroth LC 32 A20D74 (Rexroth Material Number R900912589) is a two-stage logic cartridge valve from the proven Rexroth LC series, designed for high-flow hydraulic control in industrial power units. As a slip-in cartridge valve, it functions as a pressure-compensated, pilot-operated seat element that combines the flow capacity of a large directional valve with the compact installation envelope of a cartridge insert. The main stage is controlled by a pilot pressure applied to the control chamber, allowing the valve to perform directional, pressure, and flow control functions when paired with a suitable cover plate and pilot valve. With a nominal size of NG32, this cartridge is engineered for high-volume circuits where fast response, leak-free seating, and repeatable switching behavior are essential to overall system efficiency.

Engineering Features & Advantages
- Precision Performance: The pilot-operated seat design delivers fast, defined switching with minimal internal leakage in the closed position, ensuring reliable load holding and precise flow control in high-pressure circuits.
- High Flow Capacity in Compact Form: The NG32 cartridge handles large flow volumes while occupying a fraction of the space of a comparable line-mounted directional valve, reducing manifold size and piping complexity.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction and wear-resistant internal components for extended service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
