Butterfly valve is a kind of valve that takes a disc as closing part (butterfly board) which rotates around the valve axis to achieve opening and closing. The valve is mainly used for cut-off and throttling on pipeline. A plate or disc is positioned in the center of the pipe. The disc has a rod passing through it that is connected to an actuator outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. The flow of medium may be controlled by changing deflection angle of butterfly board.
Types of Butterfly ValveBased on Structure
According to the structural form, butterfly valve can be divided into Triple offset butterfly valve, high-performance butterfly valve, metal seated butterfly valve and double offset butterfly valve. The structural difference of butterfly mainly lies in whether the stem axis, disc center, body center is in the same position or eccentric position.
