Product Details:

MOOG C41156-421 servo valve coil assembly is a precision hydraulic part designed for MOOG D661 series electro-hydraulic servo valves. This electromagnetic winding acts as the core drive component, converting incoming electrical control signals into mechanical force to push the valve spool and adjust the hydraulic oil flow. It is wound with high purity enameled copper wire and fully encapsulated by high-temperature epoxy resin. The encapsulation structure provides excellent insulation protection and safeguards the internal winding against damage from oil mist, vibration and temperature fluctuations in hydraulic stations.

This valve drive component maintains stable magnetic output under continuous industrial operation. It responds quickly to command signals from the control system and accurately changes the spool position, which directly controls oil flow rate and direction for closed-loop hydraulic regulation. MOOG C41156-421 servo valve coil assembly is widely used in metallurgical rolling mills, static and dynamic material testing machines, aerospace hydraulic test benches, heavy metal forming presses and automated hydraulic manufacturing lines.

After long service cycles, the original coil may suffer insulation aging, winding burnout or unstable magnetic response. Replacing the defective unit with this servo valve coil assembly can restore the servo valve’s original dynamic response and control accuracy, eliminate unstable hydraulic action faults and reduce unplanned equipment downtime. Every MOOG C41156-421 hydraulic part undergoes resistance testing, insulation detection and electromagnetic performance inspection before shipment. Strict quality checks guarantee good compatibility with matched MOOG D661 servo valves and reliable long-term operation in harsh industrial environments.
