Product Details

MOOG 072A560 is a two-stage mechanical feedback electro-hydraulic servo valve from MOOG 72 series. It adopts dry torque motor and dual-nozzle flapper pilot stage structure, featuring high sensitivity, fast dynamic response and low hysteresis, specially engineered for steam turbine DEH control systems and high stability precision hydraulic closed-loop control. This moog servo valve uses mechanical spool feedback design to maintain stable flow output without electronic position feedback. A replaceable first-stage filter is integrated inside the valve body, which can intercept solid contaminants in hydraulic oil, simplify field maintenance and reduce equipment downtime caused by oil pollution. The valve is compatible with fire-resistant hydraulic fluid, the standard medium used in power turbine control systems. It accepts standard analog current control signal, continuously adjusting the spool opening and converting electrical command signals into proportional hydraulic flow output to accurately control displacement, speed and force of hydraulic actuators. The valve body is manufactured with high-strength alloy material and anti-corrosion surface treatment, and can operate reliably under long cyclic working conditions. This electro-hydraulic valve is widely used in steam turbine DEH regulation systems, power generation equipment, material fatigue test benches and other heavy-duty hydraulic control scenarios. It can work with MOOG motion controllers to build complete closed-loop electro-hydraulic control systems for high stability power control projects.
