The Application of Differential Flow Adjustable Shuttle Valve in the Control of Ball Valve

The differential flow adjustable shuttle valve is an important and fundamental device to realize pipeline automation control. The paper introduces the working prrinciple and basical performance of the shuttle valve. The site test and application have shown that this valve is available not only in controlling and adjusting the on/off time of ball valve, but also in that of butterfly valve, gate valve and other valves, as well as in adjusting the flow rate and pressure of main valve.
