D10150.23-2KR.41.4CP.SA光杆蝶阀INTERAPP蝶阀加用于袖口硅代码SA的材料对应的模板美国食品和***管理局（FDA）在美国联邦法规（CFR）第守则21，段落177.2600记录。这是为了证明DASS模具硅氧烷（代码SA）衬里从与符合的材料制造联邦法规的美国食品和***管理局（FDA）规范的要求（CFR），第21177.2600款。Add the template corresponding to the material used for the cuff silicon code SA to the US Food and Drug Administration (FDA) Code 21 of the US Federal Regulation (CFR), paragraph 177.2600. This is to prove that the DASS mold silicone (code SA) lining is manufactured from materials that comply with the requirements of the Federal Food and Drug Administration (FDA) Regulations (CFR), Section 21177.2600.
D10150.23-2KR.41.4CP.SA光杆蝶阀INTERAPP蝶阀结构特性： 
■ 既适用于气态介质，也适用于液态介质。 
■ 可进行双向关闭 
■ 备选维修管道终端 
■ 一体化贯穿轴：确保阀门的强度、可靠性合阀板的***定位。 
■ O形圈：有助于防止轴泄漏。 
■ 精密准确的锥形销钉：增强防震保护，强化轴与蝶板的结合。可在现场更换。 
■ 精密准确的蝶板轮廓：防止“泡紧”关闭困难，确保程度见效扭矩，延长阀座寿命。 
■ 支撑性轴密封：弹性材料与酚醛背衬环的紧密结合体，有效防止由于扭曲变形导致的轴泄漏。 

Structural characteristics:
■ Suitable for both gaseous and liquid media.
■ Can be closed in both directions
■ Alternative maintenance pipeline terminal
■ Integrated through shaft: to ensure the strength and reliability of the valve and the *** positioning of the valve plate.
■ O-ring: helps prevent shaft leakage.
■ Precise and accurate tapered pins: enhance shockproof protection and strengthen the combination of shaft and butterfly plate. Can be replaced on site.
■ Precise and accurate butterfly plate contour: prevent "bubble tight" closing difficulty, ensure the degree of effective torque, and extend the life of the valve seat.
■ Supporting shaft seal: a tight combination of elastic material and phenolic backing ring, effectively preventing shaft leakage due to distortion.
