A?butterfly?valve?is?a?type?of?flow?control?device,?typically?used?to?regulate?a?fluid?flowing?through?a?section?of?pipe.?
The?valve?is?similar?in?operation?to?a?ball?valve.?A?flat?circular?plate?is?positioned?in?the?center?of?the?pipe.?
The?plate?has?a?rod?through?it?connected?to?an?actuator?on?the?outside?of?the?valve.?Rotating?the?actuator?turns?the?
plate?either?parallel?or?perpendicular?to?the?flow.?Unlike?a?ball?valve,?the?plate?is?always?present?within?the?flow,?
therefore?a?pressure?drop?is?always?induced?in?the?flow?regardless?of?valve?position.
