Which PRV type is expected to provide accurate control and large capacities?

The pilot-operated pressure relief valve (PRV) is designed to provide accurate control and can handle large capacities effectively. This type of valve utilizes a small pilot valve to manage a larger main valve, allowing for precise adjustments to the pressure settings. The pilot valve responds to pressure changes, ensuring that the main valve operates only when necessary to regulate pressure within the system. This mechanism allows for a higher flow rate and more stable pressure control compared to other types of PRVs.

In addition to capacity and accuracy, pilot-operated valves are particularly useful in systems that experience fluctuating pressures or require fine-tuning to maintain consistent operation. They can also be used in larger systems where maintaining exact pressure settings is crucial, making them optimal for applications in commercial and industrial contexts.
