BUTTERFLY VALVE

A Butterfly Valve is a type of flow control device, typically used to regulate fluid flowing through a section of pipe. The valve is similar in operation to a ball valve. It is from a family of valves called quarter turn valves.

Some of the salient features are:

Tight shut-off
No routine maintenance
Excellent control
Body & Steam protected from service fluid
Low installation cost
