When a valve is cycled, one can observe the quality of control by measuring and graphing the flow leaving the valve and the input operating the valve, such as electrical current (for coil controlled valves) or steps (for stepper motor controlled valves). This paper will discuss the characteristics of a valve’s performance curve—specifically, where flow begins and how the curve’s trend can indicate certain valve features and their consequences.
