等の耐蝕、耐薬品性のある非金属材料を被覆したバタフ
ライ弁において−、一端部を円形以外の横断面形状とし
た弁棒挿入部を両端に有する２枚より成る板金成型した
部材を接合し、上記弁体の弁棒と直交する方向で且周縁
部近傍位置付近に上記非金属材料が弁体の表裏融合せし

特徴とするバタフライ弁。In a butterfly valve in which the entire surface of a disc-shaped valve body made of a rigid material is coated with a corrosion-resistant and chemical-resistant non-metallic material such as synthetic resin or rubber, a valve stem with one end having a cross-sectional shape other than circular is inserted. An opening is formed in a direction perpendicular to the valve stem of the valve body and in the vicinity of the peripheral edge so that the non-metallic material fuses with the front and back surfaces of the valve body. A butterfly valve characterized in that the dimensional thickness of the peripheral edge of the valve body is formed to be the same as S゛ except for the valve stem insertion portions at both ends of the valve body so that pressure loss and fluid resistance are small when the valve is opened. .
