How to interpret a butterfly valve cv chart?
You interpret a butterfly valve cv chart by matching size with angle. Find your required flow rate first. Then scan downward toward appropriate opening percentages. This reveals proper nominal pipe sizes quickly.
Interpolation helps estimate numbers between listed values. Sometimes exact requirements fall between standard sizes. You must round up for safety normally.
Finding maximum capacity
The hundred percent column shows peak limits. Wait, there’s more: operating at maximum opens invites cavitation. Experts recommend running at mid-range capacities.
Understanding control ranges
Throttling happens best between specific angles.
- Avoid operating below twenty degrees.
- Control diminishes past seventy degrees.
- Sweet spots lie right midway.
Practical sizing examples
