Product Overview
The Eaton PRV12-12-S-0-50 (OEM reference 02-170772) is a high-performance proportional pressure relief valve engineered within the Vickers proportional valve family. This pilot-operated, solenoid-controlled valve provides infinitely variable pressure regulation proportional to the electrical command signal supplied to its proportional solenoid. Unlike fixed-setting relief valves, the PRV12 series enables precise, dynamic pressure control across the full operating range, making it an essential component in electrohydraulic systems requiring smooth pressure ramp-up, controlled decompression, and programmable pressure profiles. The valve is designed for direct integration into industrial power units and manifold blocks, delivering reliable system overload protection while simultaneously serving as an active pressure-control element in closed-loop and open-loop hydraulic circuits.
