Pilot-operated control valves are a intricate version of pressure control device utilized in a wide spectrum of industrial setups. Unlike direct-acting units , these machines leverage a smaller, internally driven "pilot" valve to control the main outlet setting. This enables for greater stability and higher capacity capabilities, particularly when managing situations involving substantial volume of fluid or gas and requiring consistent output even with changes in inlet pressure .
