Industrial PRA2520-B Flange Pilot Operated Pressure Relief Valve

The PRA2520-B Flange Pilot Operated Pressure Relief Valve, with secondary identification C-1323, is a two-stage, pilot-operated relief valve used to automatically vent excess pressure in hydraulic and process systems while maintaining a preset setpoint. This inline-flanged unit features a 10 in nominal size and a maximum operating pressure up to 350 bar (5,075 psi), compatible with hydraulic oil and industrial process fluids. Constructed from heavy-duty cast or forged metal, it uses a pilot-actuated hydraulic control to deliver high-flow relief in demanding environments such as hydraulic power units, oil and gas facilities, chemical processing plants, power generation, and injection molding machines. It conforms to ISO 6264 / CETOP design principles and is rebuilt to support reliable pressure regulation in industrial and heavy-duty fluid power systems.
