Pilot Operated Pressure Relief Valve
In this video i explained construction, working symbol and circuit of pilot operated pressure relief valve.
Pilot-operated pressure relief valves pressure relief valve offer several advantages over direct pressure relief valves, including:
Higher Flow Capacity: Pilot-operated valves can handle higher flow rates, making them suitable for larger systems. The pilot mechanism allows for greater flow through the main valve.
Better Pressure Regulation: They provide more stable and precise pressure control. The pilot valve can respond to pressure changes more effectively, maintaining the desired setpoint more accurately.
Reduced Size and Weight: Because the pilot valve controls the larger main valve, the overall size and weight of the valve assembly can be reduced compared to a direct-acting valve of equivalent flow capacity.
Improved Performance in High-Pressure Applications: Pilot-operated valves are generally more effective in high-pressure systems, where the direct-acting valve might struggle due to the force required to open against high pressure.
Less Sensitivity to System Pressure Fluctuations: They can be less affected by fluctuations in system pressure, leading to fewer unwanted trips and better overall system stability.
Ease of Maintenance: Some designs allow for easier maintenance or replacement of the pilot without taking the entire valve assembly offline, minimizing downtime.
