Product Introduction: 330180-51-10
The 330180-51-10 is a Servo Valve Coil Assembly. This component is a critical sub-assembly of an electro-hydraulic servo valve, functioning as the primary electrical-to-mechanical transducer. When an electrical control signal is applied, the coil generates a magnetic field that produces a proportional force on the servo valve's armature. This precise force is the first step in converting a low-power electrical command into a high-power hydraulic output. This part number represents a specific coil configuration with defined electrical characteristics and physical connectors, designed as a replacement or service part for a particular series of servo valves.
