A base valve assembly fore regulating the flow of fluid through a twin tube fluid vehicle damper is provided. The base valve assembly has opposing compression and rebound surfaces. Inner and outer annular seats extend from the compression surface and define an annular channel therebetween. At least one fluid passageway connects the annular channel and the rebound surface for providing fluid communication therebetween. A connector secures a blow-off valve to the cylinder end. The blow-off valve has a hollow cylindrical portion with a flange extending transversely from an end thereof. The flange is adjacent the annular seats when the blow-off valve is in a closed position. The blow-off valve is movable from the closed position to an open position away from the compression surface. A helical spring is interposed between the connector and the blow-off valve for biasing the blow-off valve to the closed position. A low speed compression bypass valve is interposed between the annular channel and the blow-off valve for permitting fluid to exit the annular channel past the blow-off valve when the blow-off valve is in the closed position. The blow-off valve provides performance during compression of the damper.
