1, the valve coefficient introduced,Determination of the valve is usually the valve coefficient, the valve coefficient, also known as valve flow coefficient. When the valve selection for special working conditions, the use of valve technology to determine the valve size, the valve can be stable under the control of process fluid can flow through the need. Valve manufacturers often publish data on all types of valves,
