This is known as the manufacturers' standard gage for sheet steel. The larger the gauge number, the thinner the metal (not applicable for zinc).
What Is The Cv Of A Control Valve. Cv and kv are 2 coefficient allowing to relate the pressure drop through a valve to the flowrate of fluid going through. Also, the valve c v is directly related to the valve opening.

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 definition is: What is rated cv of control valve?
When Sizing A Control Valve, The Most Common Approach Is To Calculate The Flow Coefficient, Cv Which Is A Measure Of The Capacity Of The Valve Body And Trim.
A valve with a cv of 10 will flow 10 gpm with a 1 psi pressure drop. For example, a control valve with a \(c_v\) rating of 45 should flow 45 gallons per minute of water through it with a 1 psi pressure drop when wide open. It is a critical part of a control loop and is an example of a final control element.
I Recommend Using The Control Valve Manufacturer Has Provided.
Valve body/ trim/ bonnet data Cv calculation for control valve sizing. As the valve cv increases its size also increases.
A Valve Cv Can Be Described As The Number Of Gallons Per Minute (Gpm) At 60 O F (15.5 O C) That Will Pass Through A Valve With An Associated Pressure Drop Of 1 Psi.
Cv value = flow coefficient in imperial units. 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 complete definition also says that the flow medium must have a specific gravity of 1000 kg/m 3 and a kinematic viscosity of 10 −6 m 2 /s.
It Is A Number Published By The Valve Manufacturer That Describes The Number Of U.s.
It applies to the factor of the head drop (δh) or pressure drop (δp) over a valve with the flow rate q. The k v factor of a valve indicates the water flow in m 3 /h, at a pressure drop across the valve of 1 kgf /cm 2 when the valve is completely open. Flow rate is expressed as cv or kv, depending on the system of measurement being used (imperial or metric, respectively).
What Is Valve Flow Coefficient (Cv)?
Flow rate (m3 / h). 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. The minimum required cv value is often listed in a valve’s product description, or wherever its specifications are found.
