Calculating the Installed Flow and Gain of a Control Valve

WebFeb 1, 2024 · One valve manufacturer suggests the following gain criteria for installed gain within the specified flow range: Gain (max) / Gain (min) < 2.0. Extremely low gains are undesirable, because a low gain means when the valve moves, the flow does not change by much. It might not be as obvious why high gains are undesirable. WebEquation 7c is used to calculate the compensation factor, which is limited to a reasonable range (e.g., 0.8 to 1.2). The resulting factor is then multiplied by the uncompensated, or raw, flow yielding the compensated flow.
