The invention provides a compensating pressure regulating valve used for steadying pressure value, comprising a valve body and a valve plug; the compensating pressure regulating valve is characterizedin that the valve plug is connected with the valve body by an obturating ring and a sealing slide bushing which is arranged between the valve body and the valve plug, a high pressure sealing ring isarranged between valve plug and the sealing slide bushing, and the sealing slide bushing and the valve body are closely fixed by a retainer ring; the other part of the valve plug is provided with an elongated sleeve, a protective casing and a manual regulation wheel, wherein, the elongated sleeve is connected with the valve body, the protective casing is arranged between the elongated sleeve and the manual regulation wheel, and the manual regulation wheel is fixed on the valve plug by a nut. The compensating pressure regulating valve provided by the invention can effectively maintain the pressure loss of a hydraulic system and keep the pressure value comparatively stable when in the loading process of the pressure value; on the premise that automation is not requested, the compensating pressure regulating valve can completely replace a hydraulic servo system.
