Natural gas gathering integrated device is one of important achievements of low cost ground supporting technology used for tight gas reservoir development and it is also the key equipment in ground system technology innovation of Changqing oil and gas field. The device is suitable for low and medium pressure and non-acidic gas gathering station and can replace conventional non pressure boost station. In its research and development, it is very difficult to combine conventional valve into a skid. Moreover, higher cost and longer procurement cycle are needed with untimely after-sale service. A new multi-function electric three-way valve was successfully developed based on field research, result analysis, scheme comparison, structural design, and factory manufacture and field test. Such valve can reduce procurement cost by more than 20 %, shorten procurement cycle by more than 50 %. The successful development of the valve can not only meet requirement of the integrated device and solve the problem in research and development effectively, but also fit in with low cost strategy development of Changqing Oilfield Company and it is more beneficial to application and promotion of the integrated device.
