Week 14 challenge

Butterfly valves

Butterfly valves are quick and easy to open and close, and operators can use them to start, stop and regulate flow. Butterfly valves can be used in their complete open or closed positions and even for non-critical throttling applications.

The three main types: zero, double, or triple offset.
