Product Presentation:

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. Butterfly valve is suitable for pipeline that transports various corrosive, non-corrosive fluids in producer, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power environmental protection, building water supply and drainage and other engineering systems for regulating and cutting off medium flow.
