D10150.23-2KR.41.4CP.SA光桿蝶閥INTERAPP蝶閥加用于袖口硅代碼SA的材料對應的模板美國食品和***管理局（FDA）在美國聯邦法規（CFR）第守則21，段落177.2600記錄。這是為了證明DASS模具硅氧烷（代碼SA）襯里從與符合的材料制造聯邦法規的美國食品和***管理局（FDA）規范的要求（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光桿蝶閥INTERAPP蝶閥結構特性： 
■ 既適用于氣態介質，也適用于液態介質。 
■ 可進行雙向關閉 
■ 備選維修管道終端 
■ 一體化貫穿軸：確保閥門的強度、可靠性合閥板的***定位。 
■ O形圈：有助于防止軸泄漏。 
■ 精密準確的錐形銷釘：增強防震保護，強化軸與蝶板的結合。可在現場更換。 
■ 精密準確的蝶板輪廓：防止“泡緊”關閉困難，確保程度見效扭矩，延長閥座壽命。 
■ 支撐性軸密封：彈性材料與酚醛背襯環的緊密結合體，有效防止由于扭曲變形導致的軸泄漏。 

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.
