Abstract
This paper introduces the operation and the principle of shuttle controlled ball valve in pipeline transportation,and introduces the basic characteristic of an important element Adjustable Differential Flow Shuttle Valve ADFSV〔1〕in the shuttle controlled actuator,where the ADFSV as a speed control element can control gas/hydraulic actuators of ball valves,butterfly valves,gate valves,etc.Through a lot of experimental research,analysis,and simulation actuator test,it is proved that the shuttle controlled ball valve can prevent water hammer phenomena in pipeline transportation,damp fluctuation in gas transportation,and provide aa wider speed adjustment range.
