ABSTRACT:
A butterfly valve apparatus includes a valve body, valve discs, valve shafts, and a connecting member. The valve body has valve passages. Valve discs are respectively arranged in the valve passages. Valve shafts are supported by the valve body such that the valve shafts are aligned substantially in the axial direction of the valve shafts. The plurality of valve shafts respectively support the valve discs. The connecting member connects the valve shafts, which are adjacent to each other. The valve shafts are formed of metal. The connecting member is formed of resin. The valve shafts, which are adjacent to each other, form a gap therebetween in the axial direction of the valve shafts. The valve shafts are connected by forming the connecting member.
