Product Overview
The Rexroth LT 05 MKA-31/025/02M12 (Material Number: R901055189) is a precision-engineered pilot control valve belonging to the Rexroth directional spool valve family. Designed and manufactured by Bosch Rexroth, this valve serves as a compact, manually actuated pilot control unit that delivers precise, proportional hydraulic signals to the main directional control valves in a system. The LT 05 series operates on a proven spool-in-sleeve working principle, where axial displacement of the control spool within a precision-machined sleeve meters pilot oil flow and pressure to downstream main stage valves. With a nominal size of 05 and a flow rate designation of 025, this valve is optimized for low-flow pilot circuits requiring high sensitivity and repeatable actuation. Its robust construction and finely tuned spool geometry make it an ideal choice for demanding industrial hydraulic systems where accurate directional control and smooth proportional response are critical to overall machine performance.

Engineering Features & Advantages
- Precision Spool Metering: The finely machined control spool and sleeve assembly provides accurate, proportional pilot pressure output with minimal hysteresis, ensuring smooth and repeatable directional control of main stage valves.
- Compact Pilot Stage Design: The NG 05 size and 025 flow designation deliver optimized pilot oil flow for sensitive low-volume control circuits without sacrificing response speed or actuation force.
- Robust Spool-in-Sleeve Construction: Hardened and ground spool surfaces resist wear, contamination, and spool sticking, ensuring long service life even in high-cycle industrial duty.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, including high-pressure pilot circuits and demanding duty cycles.
- Direct Fit Replacement: Precision-manufactured to original REXROTH specifications for direct replacement, minimising downtime and eliminating fitment issues.
