本蝶閥采用的是三維偏心原理設計，是在原有的雙偏心基礎上增加了一個獨特的偏心，不僅利用了原有的凸輪效應，而且完全消除了90度旋轉中閥板與密封圈之間的全部磨擦。
通過優化了蝶板密封面與閥座密封圈之間接觸角的特性，閥門接觸角大于鎖定錐角范圍。從幾何形狀看，排除了蝶板卡死的可能性，從而確保閥門開關所需扭矩。蝶板密封面可以鑲不銹鋼密封圈或在蝶板上直接堆焊不銹鋼或硬質合金，可確保閥門在各種用途包括高溫和不潔工況下耐用。主要零件材料：零件名稱材料閥體鑄鐵、不銹鋼、鉻鉬鋼、合金鋼蝶板鑄鋼、合金鋼、不銹鋼、鉻鉬鋼密封圈不銹鋼與耐高溫石棉板組合成多層次閥桿2Cr13、1Cr13不銹鋼、鉻鉬鋼填料柔性石墨D3（6、9）43H-6～10（C、P、R、V）系列連接尺寸：公稱通徑DN外形尺寸連接尺寸LHD343HD643HD943HPN0.6MPaPN1.0MPa短長H1A1B1H2A2B2H3A3B3DD1z-dDD1z-d50108150112350180200605245725302502551401104-141651254-1865112170115370180200625245725502502551601304-141851454-1880114180120380180200645245725652502551901504-182001608-18100127190138420180200675355926002502552101704-182201808-18125140200164460180200715355926402502552402008-182502108-18150140210175555270280800355927053003152652258-182852408-2220015223020860527028085025017077530031532028012-183402958-2225016525024368027028092525017094530031537533512-2239533012-223001782702838003804201035450220107030031544039512-2244540012-223501902903108353804201070450220114030031549044516-2250546016-224002163103409154504701190450280121030031554049516-2256551516-264502223303809604504701250650280133557571459555016-2261556520-2650022935041010204804901295650280141557571464560020-2267062020-2660026739047012256406601455850380160565681075570520-2678072520-3070029243055013556406601585850380184465681086081024-2689584024-30800318470640147064066017001250380204065681097592024-30101595024-3390033051071015458509001865125038022557858631075102024-301115105028-33100041055077017958509002015150058023807858631175112028-301230116028-36120047063089019658509002226150058026407858631405134032-331455138032-3914005307109202380     2886  1630156036-331675159036-42160060079010852956     3156  1820176040-331915185040-54180067087012303221     3421  2045197044-422115202044-54200076095013503485     3685  2265218048-482325223044-54
