How to Use Flow Coefficients (Cv) for Hydraulic Fluids

WebIt should be noted that in reality the pressure drop across a control valve will normally rise due to pressure shifts within the hydronic system. These effects were not considered in the example. The pressure shifts are discussed in Engineering Report H110 and H112. The net effect of the pressure shifts is to increase the uncontrollable flow rate. WebP1 = pressure drop across the valve fully openP2 = pressure drop in remainder of the circuit, valve fully open. A typical circuit is shown diagrammatically below. In order to maintain reasonable control without undue pressure drop the value of "N" should be ideally between 0.5 and 0.7 but never less than 0.3.
