Product Introduction: 330780-51-05
The 330780-51-05 is a Servo Valve Coil and Connector Assembly. This component is a critical electrical sub-assembly for an electro-hydraulic servo valve. It consists of a high-precision solenoid coil, often in a dual configuration for push-pull operation, potted in a robust housing with an integrated electrical connector. Its function is to convert an electrical control signal (a current) into a precise proportional magnetic force. This force acts on the servo valve's armature, initiating the first stage of converting a low-power command into a high-power hydraulic output to control an actuator.
