Cv Value For Air Valves. By definition, a cv value of one is the cv required to flow one gallon per minute (gpm) of water at 60� f with a pressure differential of one psi. Density 0.86 air = 1. Cv = (25 gpm) (1 / (1 psi))1/2. The valve flow coefficient, cv, is the number of u.s.

On valves or orifices with other cv factors, the flow capacity will be directly proportional to the cv rating. However, there is a problem with using this equation in pneumatic applications. Gallons per minute of water at 60°f that will flow through a control valve at a specified opening when a pressure differential of 1psi. Flow capacity cv values are often listed in manufacturer�s catalogs because it is a convenient way of characterizing the flow capacity of the part. Kv = 0.865 · cv cv = 1,156 · kv (equivalence between flow coefficients kv and cv) Cv is based on the volume flow rate of water at 60°f through a device within one minute at a 1 psi differential.
For example, a valve with cv of 4.00 will pass 4 times as much flow at the same pressure difference as shown in the chart.
This calculator can be used to help select a valve with enough flow capacity for a given application. For air flow at room temperature, when the outlet pressure is less than 1/2 the absolute inlet pressure, the flow becomes quite simple (although it reaches sonic velocity internally). The cv, or flow coefficient of the valve, plays a much larger part in the valve’s performance than determining how many gpm (gallons per minute) can pass through the valve. The required cv range for this application than is.0141 to.0703. Flow coefficients cv values the flow coefficiency (cv) of a valve is the rate of gallons per minute of water at 60° f through a fully opened valve at a pressure drop of 1 psi across the valve.

It allows you to calculate the flow or c v (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points in a network transporting a liquid or gas) and the flow rate. Gas relative density（air = 1） 【notes on use】 ※1 please handle the calculation result as reference value. A valve that is sized correctly is a valve that is quiet, has accurate flow control, lasts beyond its expected life span, and does not leak. Because cv is perceived as a complex expression, many designers avoid learning about it and, hence, become ignorant of its importance and proper application. The cv value of.0141 is reached at approximately turn 2.3, while the cv value of.0703 is reached at approximately turn 14.6.

For example, a cv of 150 would then equate to 150 gpm of water at 60� f with a differential pressure of one psi. How do we get value 1.156 (conversion factor) in formula cv = 1.156kv or cv= 1.156×q×sqrt (g/delta p). For air flow at room temperature, when the outlet pressure is less than 1/2 the absolute inlet pressure, the flow becomes quite simple (although it reaches sonic velocity internally). The valve flow coefficient (c v) is a convenient way to represent flow capacity of a valve across a range of fluids and process parameters.the c v calculator will calculate either c v or flow using the supplied additional parameters of fluid, inlet and outlet. For example, a valve with cv of 4.00 will pass 4 times as much flow at the same pressure difference as shown in the chart.

Scfm air flow through a valve orifice having a cv factor of 1.00 The cv value of.0141 is reached at approximately turn 2.3, while the cv value of.0703 is reached at approximately turn 14.6. For measuring the valve capacity of control valves, the coefficient cv or its metric equivalent kv is adopted. Cv value is an imperial measure of flow in us gallons per minute of water at 60° fahrenheit with a pressure drop of 1 psi across the valve.

This is used as a guide and is not a linear progression. The cv, or flow coefficient of the valve, plays a much larger part in the valve’s performance than determining how many gpm (gallons per minute) can pass through the valve. However, there is a problem with using this equation in pneumatic applications. Cv = qg (g x t) 816 x p1 qg = cv 816 x p1 g x t note: The valve�s flow coefficient, cv, is a value that is determined by flow testing for each valve size.
