Product Details

MOOG A08KO4M0VMJ is a custom high-performance two-stage mechanical feedback electro-hydraulic servo valve, specially manufactured for heavy-duty and high-precision closed-loop hydraulic control systems. This moog servo valve adopts polarized torque motor and dual-nozzle flapper pilot stage structure, bringing excellent dynamic response, ultra-low hysteresis and outstanding repeatability during long-term continuous cyclic loading operations. It uses mechanical spool feedback to maintain stable hydraulic flow output without electronic spool position feedback, and can keep consistent control performance under industrial vibration and ambient temperature fluctuation. A field-replaceable first-stage filter is integrated inside the valve body to trap solid particulate contaminants in hydraulic fluid, protect the finely machined internal components of the servo valve, reduce maintenance frequency and avoid unexpected system downtime. It receives analog current command signals, drives the torque motor to adjust spool opening, and converts electrical command signals into proportional hydraulic flow output, which can precisely control the displacement, speed and loading force of hydraulic actuators. The valve body is precision machined from high-strength alloy steel with anti-corrosion surface treatment, compatible with mineral oil and fire-resistant hydraulic fluid. This custom electro-hydraulic valve supports 3-way and 4-way hydraulic circuit layout, widely used in large material fatigue test benches, aerospace structural loading test systems, heavy-duty automotive component durability test equipment and multi-channel hydraulic simulation platforms. It can cooperate with MOOG digital servo controllers to build complete multi-axis synchronous electro-hydraulic closed-loop control systems for heavy industrial loading and motion control projects.
