    Ball Valve An Overview Sciencedirect Topics

    The ball valve is an inexpensive alternative to other valves. Ball valves use a metal ball with a hole bored through the center, sandwiched between two seats to control flow. Used in many hydrocarbon process applications, ball valves are capable of throttling gases and vapors and are especially useful for low-flow situations. These valves are quick opening and provide a very tight closure on ...
