Centerline Butterfly Valves

Main features: The valve stem and the center line of the butterfly plate of the centerline butterfly valve are in the same straight line and perpendicular to the center line of the valve body hole. During the closing process, the valve disc sealing surface contacts the valve body rubber seat to form a tight seal. The centerline butterfly valve is widely used in petroleum, chemical, metallurgy, hydropower and other industries.
