A pilot-operated valve effectively utilizes a small pilot signal to control a larger valve mechanism. This design is fundamental to the operation of pilot-operated valves, as it allows for precise control of larger airflows using minimal energy input. In essence, the pilot signal, often generated by a smaller valve or a different source, initiates the opening or closing of a larger main valve.

This method contrasts with direct manual operation, which lacks the efficiency and automation provided by pilot signals. Additionally, unlike mechanical solutions such as gravity or electric signals, pilot operation utilizes pressure differentials, making it well-suited for situations where operators need to manage significant airflow without the complexity or energy demands associated with other methods. This approach enhances efficiency and responsiveness in pneumatic systems, allowing for rapid adjustments to airflow as needed based on the pilot signal's input.
