UNKNOWN C-1323 PRA2520-B FLANGE PILOT OPERATED PRESSURE RELIEF VALVE REBUILT

Description:

The UNKNOWN C-1323 PRA2520-B Flange Pilot Operated Pressure Relief Valve is a hydraulically actuated pressure relief valve used in industrial fluid power and process systems to protect equipment from overpressure conditions and maintain safe operating pressures. Commonly installed in hydraulic power units, oil and gas facilities, chemical processing plants, power generation systems, and heavy industrial machinery requiring high-flow pressure protection. Maintenance teams, OEMs, and hydraulic system integrators use this rebuilt valve for replacement, retrofit, and repair projects to restore system safety and reliable pressure regulation.

Applications:

The UNKNOWN C-1323 PRA2520-B Flange Pilot Operated Pressure Relief Valve is used to automatically relieve excess pressure in hydraulic and process systems while maintaining a preset operating pressure. It is commonly found in hydraulic power units, oil and gas processing facilities, chemical plants, power stations, injection molding machines, and industrial process equipment where high-flow pressure control and overpressure protection are critical for safe operation. Pilot-operated relief valves are preferred in demanding applications because they provide stable pressure control with minimal pressure drop.
