Product Details

MOOG 72A-560 is a member of MOOG famous 72 series two-stage mechanical feedback electro-hydraulic servo valve, engineered for high flow and heavy-duty precision closed-loop hydraulic control systems. This moog servo valve adopts dry torque motor and dual-nozzle flapper pilot stage structure, which delivers outstanding dynamic response, low hysteresis and superior repeatability during continuous cyclic loading operations. It uses mechanical spool feedback to maintain stable hydraulic flow output without electronic spool position feedback, keeping consistent control performance under vibration and temperature variation in harsh industrial environments. A field-replaceable first-stage filter is integrated inside the valve body, which can trap solid contaminants in hydraulic fluid, protect the precision internal components of the servo valve and reduce maintenance cycles and system downtime. It accepts standard analog current command signals, driving the torque motor to adjust spool opening and convert electrical command signals into proportional hydraulic flow output, so as to precisely control 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 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 automotive component durability test equipment and multi-channel hydraulic simulation platforms. It can be matched with MOOG digital servo controllers to build complete multi-axis synchronous electro-hydraulic closed-loop control systems for heavy industrial loading projects.
