Cv Flow Coefficients of Ball Valve The coefficient of flow or C v Value is the number of US gallons of water the valve will pass with a differential pressure of 1psi through the valve at 60F. K v is the metric value of C v and is calculated as K v =C v x 0.85.

The controller and valve together form a basic control loop. The control valve is seldom full open or closed but in an intermediate position controlling the flow of fluid through the valve. 2008-05-19 2010-12-14 Alibaba.com offers 2,880 cv valves products. A wide variety of cv valves options are available to you, such as material, structure, and media.

Cv valve

It is commonly understood that nearly every pneumatic device creates a flow restriction in the system. CV Control Valve. The less the Cv, the smaller the hole, or the more resistance the valve offers to fluid passage. When a regulating control valve is fully open, it’s through-hole is the largest it can be, and its CV will have the maximum value. As the valve closes, the hole will decrease, and Cv will be less.

The Cv vs valve position is exactly what im looking for. The only thing i can find is wide open Cv. The Ashrae characteristic curve show the % flow vs valve travel.

It applies to the factor of the head drop (Δh) or pressure drop (ΔP) over a valve with the flow rate Q. Calculating control valve CV When Sizing (calculating which size valve is needed for your application) a control valve specialist needs to calculate the flow coefficient. The Cv tells you how to properly size your valve so it has minimal effect on the hydraulic efficiency you’ve engineered into your system. It is a number published by the valve manufacturer that describes the number of U.S. gallons that can pass through a valve (in a fully open position) at a pressure drop of 1 PSI. Why You Should Care Cv by definition is the number of gallons per minute (GPM) a valve will flow with a 1 psi pressure drop across the valve. For example a valve with a Cv of 10 will flow 10 GPM with a 1 psi pressure drop.

The valve flow coefficient, Cv, is the number of U.S. 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 is applied across the valve: The metric equivalent of Cv is Kv, which is defined as the amount of water that will flow in m3/hr with 1bar pressure drop.

Cv & Kv Fraction vs Angle Closure Curve Chart. This graph shows the Cv or Kv valve fraction vs opening and closing angle of a full bore ball valve: The full closure curve of a ball valve is then the above graph multiplied by the valve’s flow coefficient or factor.
