4 Steps to Valve Selection The steps described in this section will help you identify the performance criteria needed to meet your application requirements and select the right valve. Begin by calculating the valve flow coefficient (CV) using: operating pressure differential; flow rate for your application; Specific Gravity; and in some circumstances, temperature. If you already know your CV please go directly to Step 2. CV combines the effects of all flow restrictions in the valve into a single number. CV represents the quantity of water, at 68°F and in gallons per minute (GPM) that will flow...

An important note regarding Cv and valve function: The Cv calculated will apply to either the Body Orifice or the Stop Orifice depending on For example, the Stop Orifice for a 3-way normally closed valve, when de-energized, is the exhaust port. In other words, Cv is calculated using the specific Inlet Pressure (P1) and Outlet Pressure (P2) for the flow paths described below.
