How do you calculate CV for liquid flow?

What is a good CV value? A good CV value depends on the specific application and requirements. A higher CV generally indicates a valve or orifice with better flow capacity.

What CV is too high? A CV value that is too high for a given application may result in excessive flow, leading to inefficiency or instability in the system. It’s important to select a CV value that matches the desired flow rate and control requirements.

What happens when CV is high? When CV (Flow Coefficient) is high, it indicates that a valve or orifice has a greater flow capacity, which can result in a higher flow rate for a given pressure drop.

Is high CV good or bad? Whether a high CV is good or bad depends on the specific application. High CV values are desirable when a large flow rate is needed, but they can be problematic if they exceed the system’s capacity or control requirements.
