Product Overview
The Eaton PR30P20SGV is a pilot operated pressure relief valve from the Eaton PR series, engineered to protect hydraulic circuits from excessive pressure by diverting flow back to tank when the preset cracking pressure is exceeded. The two-stage pilot operated design combines a small pilot relief stage with a balanced main spool, delivering precise pressure control, minimal pressure override, and stable operation across a wide flow range. With a nominal size of 20 (NG20 / SAE 20 interface) and a G-type adjustment configuration, this valve is suited for continuous-duty industrial power units, accumulator circuits, and system protection in high-pressure hydraulic installations.
