The Protractor Group is a functional measuring component used during servo valve setup and adjustment procedures and used to identify the center position of the servo valve, ensuring correct neutral alignment before operation. Allows accurate determination of full speed positions in both forward and reverse directions. Improves operational accuracy by ensuring the servo valve reaches the correct operating positions during adjustment and testing.Attributes:• Identifies the full speed forward position of the servo valve accurately.• Helps ensure correct neutral positioning of the servo valve.• Reduces adjustment errors during servo valve setup.Applications: The Protractor Group is used during servo valve adjustment and calibration, where it determines center, full speed forward, and full speed reverse positions. It provides accurate reference points to ensure correct valve movement, controlled direction changes, and reliable system response during operation.
