Service has become an important value creation and a competitive tool in manufacturing industries against the knowledge-economy and globalization of economics. It is manufacturers and their customers together in the interactive value-creating processes who create the service value. It is supported that the potential service value streams exist and merge with the common value activities in manufacturing firms, so service process reengineering is necessary for manufacturing firms to capture service value.  Firstly, manufacturing firms should take more care for the joint of Push and Pull processes during the transformation from traditional manufacture managing patterns to service management ones.  Secondly, manufacturing firms need to redesign and reconstruct their service value chain. Thirdly, manufacturing firms must link series of inside value activities into an organic integrated body and aim at servicizing.  Taking a manufacturing firm, Dongfang Steam Turbine Works in China (DFSTW) an example, the service innovation process of manufacturing firms and the reconstruction of service value processes were also explained.
