Control valve and instrumentation terminology. The speed of sound in steam will depend upon the steam temperature and the quality of the steam, but can be calculated from equation 6.4.2 if the conditions are known (mach. 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 cv of a valve never changes unless you make any modifications to the valve�s physical characteristics. It is usually considered that the control valve will produce unacceptable noise if the velocity of dry saturated steam in the control valve outlet is greater than 0.3 mach. For example a valve with a cv of 10 will flow 10 gpm with a 1 psi pressure drop.

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).

The cv affects all of these things. The characteristic of the control valve chosen for an application should result in a direct relationship between valve opening and flow, over as much of the travel of the valve as possible. Chapter 3 covers valve and actuator types. When gas, instead of liquid flows through this valve does the cv remains same. The cv affects all of these things.

What is the cv and kv of a control valve ? 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). It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. The cv of a valve never changes unless you make any modifications to the valve�s physical characteristics. Check out the definition of cv to understand more clearly.

The characteristic of the control valve chosen for an application should result in a direct relationship between valve opening and flow, over as much of the travel of the valve as possible. Cv is commonly called the flow coefficient and kv is commonly called the flow factor. They express coefficient cv/kv as the flow rate of water in g.p.m. It applies to the factor of the head drop (δh) or pressure drop (δp) over a valve with the flow rate q.

Control valve and instrumentation terminology. 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. Therefore, the main differences between different flow coefficients come from the type of valve, and of course the opening position of the valve. Say in a liquid service the installed cv of a control valve is 120. The formula will differ depending on the product the valve regulates, such as liquid, gas, or steam.

Chapter 4 describes digital valve controllers, analog positioners, boosters, and other control valve accessories. 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: Control valve cv refers to the flow coefficient of the valve. The standard equation for a valve�s capacity in liquid service is: The speed of sound in steam will depend upon the steam temperature and the quality of the steam, but can be calculated from equation 6.4.2 if the conditions are known (mach.

This depends on how the valve has been designed to let the flow going through the valve. 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. The flow coefficient for a control valve which in full open position passes 25 gallons per minute of water with a one pound per square inch pressure drop can be calculated as: Chapter 5 is a comprehensive guide to selecting the best control valve for an Check out the definition of cv to understand more clearly.

Involves velocity, pressure, density and temperature as functions of. When gas, instead of liquid flows through this valve does the cv remains same. When flow is in the reverse direction, the port area opens fully to allow unrestricted flow. It is a number published by the valve manufacturer that describes the number of u.s. Involves velocity, pressure, density and temperature as functions of.

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. The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. Do you mean the definition for cv with respect to a valve�s capacity. Therefore, the main differences between different flow coefficients come from the type of valve, and of course the opening position of the valve.

Q = cv(dp/sg)^0.5 this assumes there is no flashing or cavitation of the fluid. Involves velocity, pressure, density and temperature as functions of. When a valve is too small for a given application you obviously won’t be able to get enough flow through the valve. The below cv values are used to give an indication of flow rates for ball valves. They express coefficient cv/kv as the flow rate of water in g.p.m.

The formula will differ depending on the product the valve regulates, such as liquid, gas, or steam. No kv is 86.5% of cv, 100% cv is the maximum the valve will pass, we used to size for valve operation around 70%, now the norm is more like 40% requiring much larger safeties (if) the control valve is the limiting basis.
