What Is Control Valve Rangeability at Leroy Gonzales blog

What Is Control Valve Rangeability. Valve rangeability is the ratio between maximum and minimum controllable flow through the valve. It is the ratio between the maximum and minimum controllable flows. Some valves can handle a large range of flow rates, whereas others excel in a smaller range. Rangeability refers to a control valve’s inherent characteristic; The term rangeability is exclusive to the. The turndown factor of the valve refers to the operation of that valve (with actuator) installed in a system as a ratio. By definition, rangeability refers to the valve body only. Inherent rangeability is defined as the change in. For manufacturers, it’s usually 50:1 for equal percentage, 33:1 for linear and 20:1 for equal percentage valves, with a minimum controllable flow (not leakage, but controllable) down to about 2%. Basically, there are two definitions of rangeability: When considering liquid control valves, the ratio of maximum flow to minimum controllable flow at constant pressure drop across the valve is. One for inherent rangeability, and the other for installed rangeability.
