So when you say an installed cv of 120, it means the valve�s cv is 120. Go to online calculation of the flow coefficient cv and kv. 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. 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. The valve flow coefficient cv or its metric equivalent kv has been adopted universally as a comparative value for measuring the capacity of control valves.

The cv refers to the amount of energy released when a known volume of gas is completely combusted under specified conditions. Modeling a device characterized by a cv value engineered control valve flow characteristics learning water control valves flow coefficient i c sub v sub i. The flow coefficient, cv, is a dimensionless value that relates to a valve’s flow capacity. 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.

For convenience, flow capacities for the most commonly used couplings are presented on graphs. They express flow coefficient cg or kg as the flow rate of water in g.p.m. 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. Valve flow coefficient (cv) is a valve’s capacity for a liquid or gas to flow through it. ※3 for p1 and p2, please use pressure close to the valve.

So you need to check whether the calculated cv for the new fluid (gas) is more than the installed valve�s cv (120). They express flow coefficient cg or kg as the flow rate of water in g.p.m. It is commonly understood that nearly every pneumatic device creates a flow restriction in the system. C v & flow calculator. This value is a coefficient used to predict flow through a particular valve based on a specific pressure drop across it.

The below cv values are used to give an indication of flow rates for ball valves. 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. So you need to check whether the calculated cv for the new fluid (gas) is more than the installed valve�s cv (120). Valve flow coefficient (cv) is a valve’s capacity for a liquid or gas to flow through it. This is the basic equation for cv, where q is the rate of flow (gallons per minute), sg is the specific gravity of the fluid, and p is the pressure drop across the valve (psi).

So when you say an installed cv of 120, it means the valve�s cv is 120. Valves are tested by running water through it before publishing the cv value. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. I haven�t worked on this stuff for a while, so i reviewed the derivation of the classic cv equation. They express flow coefficient cg or kg as the flow rate of water in g.p.m.

This derivation assumes the fluid is incompressible. C v calculator for valve sizing. Q = valve flow rate in gallons per minute (us gpm) δp = difference between upstream and downstream pressure in For a specific gas control valve, the flow coefficient cg or kg is determined experimentally by control valve manufacturers, and you can found it in manufacturers technical specifications. It is technically defined as “the volume of water at 60°f (in us gallons) that will flow through a valve per minute with a pressure drop of 1 psi across the valve.”

A simplified version of the cv formula for sub critical gas pressure drop is shown below: For a specific gas control valve, the flow coefficient cg or kg is determined experimentally by control valve manufacturers, and you can found it in manufacturers technical specifications. However, this same cv value can be used to determine gas flows through a valve. The valve flow coefficient cv or its metric equivalent kv has been adopted universally as a comparative value for measuring the capacity of control valves. The adjusted cv (or kv) value should be based on the cv or kv formula for sub critical gas pressure drop.

Gallons per minute that passes through a valve at a pressure drop of 1 psi. How do convert cv to cg ? Control valve cv refers to the flow coefficient of the valve. So when you say an installed cv of 120, it means the valve�s cv is 120. The effective pressure drop across a gas control valve depends on the properties of the gas flowing through the valve and the valve design.

Its most basic form is q=flow rate and p=pressure drop across the valve. Calorific value (cv) is a measure of heating power and is dependent upon the composition of the gas. However, this same cv value can be used to determine gas flows through a valve. This is used as a guide and is not a linear progression. Therefore, the main differences between different flow coefficients come from the type of valve, and of course the opening position of the valve.
