If you calculated a Cv value of 47, you would want to choose the 3-inch valve because in the 2-inch, 47 would fall outside of our recommended range. 如果您计算的Cv值为47,您将希望选择3英寸阀,因为在2英寸中,47将超出我们的推荐范围。 If you calculated a Cv of 35, it falls in the r...

If you calculated aCv of 35, it falls in the range for both valves. In this case we would recommend the 3-inch because it falls closer to the middle of the flow curve. How to Size a Control Valve The first question you need to ask when valve sizing is “What is my pressure?” ...
Valve Cv applies to the coefficient of pressure drop(ΔP) or head drop (Δh) on the valve of Q(flow capacity). This article will tell you everything about the valve cv.

Control valvesDRAG discFlow capacity (Cv)Establishing the true flow capacity of a control valve is often times critical. The two most common methods for establishing control valve capacity are mathematical modeling and laboratory flow testing. Unfortunately, developing an accurate analytical model usuall...
