Product Overview
The Rexroth LT 07 MKA-2X/100/02M (Material Number: R900905257) is a precision-engineered hydraulic pilot control valve belonging to the Rexroth directional spool valve family. This unit functions as a manually actuated, direct-operated directional control valve designed to pilot larger main-stage directional valves or to directly control small-to-medium flow hydraulic circuits. The valve operates on a spool-in-sleeve principle, where axial displacement of the precision-ground spool within the hardened sleeve opens or closes metering passages to direct pressurized fluid to the desired work port. With a nominal size of NG 7 and a maximum operating pressure of 100 bar, the LT 07 MKA-2X/100/02M is ideally suited for pilot oil supply, control signal generation, and low-pressure directional control tasks within complex industrial hydraulic systems. Its robust design and precise metering characteristics ensure reliable, repeatable performance in demanding B2B environments.

Engineering Features & Advantages
- Precision Spool Metering: The hardened, precision-ground spool and sleeve assembly ensures accurate, repeatable flow control with minimal internal leakage, enabling fine pilot signal modulation for downstream main valves.
- Manual Actuation Reliability: The MKA-2X actuation mechanism provides direct, tactile operator control with a robust mechanical linkage designed for high-cycle industrial use without drift or loss of detent.
- Compact NG 7 Design: The small nominal size allows for space-saving integration into dense hydraulic manifolds and pilot control blocks without sacrificing performance.
- Industrial Reliability: Designed for dependable long-term operation in demanding industrial environments, with quality bearings and sealing systems ensuring extended maintenance intervals.
- Direct Fit Replacement: Precision-manufactured to original REXROTH specifications for direct replacement, minimising downtime and eliminating fitment issues.
