We at simulationHub are always on the lookout for any assistance to help you with valve problems. Let's have a look at a recent project involving ball valve Cv determination.
What exactly is Cv?
The process industry has varied applications of valves. The operating conditions can vary significantly as well. Cv, also known as valve flow coefficient is a number which relates the flow rate with a given pressure drop across the valve.
A process engineer is always facing the question of "What is the right size, flow characteristics and rating of the valve that I can add to the system?" He has to calculate the major and minor losses that the system will face and come up with a system design that fulfills the requirements. Valves are a very critical part of these systems. In selection of valves, the focal points are the valve flow characteristics i.e Cv. So the process engineer will look up to the valve manufacturer's design catalogues and select the valve for given flow requirements.
This is where the challenge appears. Read the full article here.
