Product Overview

This main relief valve, part number SA727030160 (also marked SA7270-30160), serves as a critical pressure control component fitted inside the hydraulic system of Volvo excavators. It regulates and releases excess pressure within hydraulic circuits, limiting the maximum working pressure to shield the main hydraulic pump and valve block from damage caused by overload and sudden pressure spikes. The relief valve delivers stable pressure performance in heavy-duty working environments. It is engineered to match the original installation dimensions, allowing for direct replacement. Cross reference part numbers VOE14552089 and SA823036590 are interchangeable with this valve, fitting a wide lineup of Volvo medium and large crawler and wheeled excavators across B, C, D and E series.
