Cv Valve Unit Of Measure. Select a nominal valve size from the cv charts based on the calculated cv. Because it provides an empirical coefficient good to. Go to online calculation of the flow coefficient cv and kv. The cv was designed for use with liquid flows, it expresses the flow in gallons per minute of 60º f water with a pressure drop across the valve of 1 psi.

What is the cv of a valve? Because it provides an empirical coefficient good to. In deciding the size of the control valve that (port size) we need to calculate the cv value of the process (calculated cv) by calculating cv has educated more than 50 years, which is involved in. From cv table, the corresponding valve position is 70% open. Selecting the right size valve is an important part of the process, but there are other equally important considerations as well. For example, weight is a physical quantity.
Relationship between gpm, cv, δp.
A valve has a published cv of 5.4 on 60°f water. The flow resistance will be 29 times greater on 150 ssu. The rated fl is the actual fl value for a particular valve and trim style. In the chart below, we show the approximate cv value of butterfly valves ranging from 2 to 24 and at various disc angles. It is a unit of measure for comparing valve flows. In other words, flow capacity is a measure of efficiency at allowing liquid to flow.

Because it provides an empirical coefficient good to. Olynyk, in my opinion, cv is not derived from any equation in particular, but empirically defined (and measured) as the flow rate which flows through a valve at a given travel referred to 1 psi of dp across the valve and water at room temperature; When control valve professionals talk about control valve sizing, they really mean the entire process of selecting the valve that will do the best job of controlling the process. Valve sizing technical bulletin scope valve size often is described by the nominal size of the end connections, but a more important measure is the flow that the valve can provide. It describes the amount of water from 5° to 30°c which flows through the valve at a pressure loss of 1 bar.
