Actuation-
Butterfly valves can be operated by a lever for smaller valves or gears for larger sizes. All Butterfly valves can additionally have automatic gears by use of electric, pneumatic or hydraulic power.
Application-
Butterfly valves can be used above ground or buried service (certain design types) applications. They have a low head-loss and commonly used to throttle or modulate. On distribution water lines they are the valve of choice 12″ and larger.
