The Pilot Operated Globe Control Valve leverages pilot operation to manage fluid flow effectively. The primary force needed to open the valve comes from the media pressure, with the pilot controlling a small diameter impulse line that activates the main diaphragm or piston. This design allows for precise control over fluid flow by adjusting the size of the flow passage, directly influencing process variables such as liquid level, temperature, and pressure. In automated control systems, this valve serves as the final control element, adjusting flow rates based on controller inputs to maintain desired process conditions.
