Cast Top Entry Ball Valve：Specification：2& quot; ~ 36& quot;(DN50~DN900)ANSI Ratings 150# ~ 1500# (PN16~PN50)RF RTJ BW ConnectionMain Body Material :?ASTEM A216 WCB,LCB ,A217 WC1,WC9,C5,ASTM CF8,CF8M,CF8C,CF3,CF3M.Main Ball Material:?ASTM A105, A182 304, A182 316, A182 304L, A182 316L,A182 F6A,A182,F51,A182 F53,F22 AlloyMain Seats Material:?PTFE/ RTFE(≤120℃) , NYLON (≤80℃), PEEK/PPL ?(≤250℃)Product DetailsThe cast top-entry ball valve is designed as an integrated valve body and easy for machining , so as to ensure that it has enough strength and rigidity under the maximum rated working pressure. Its support and ball rod fixed by an upper-assembled pivot and an integrated pivot respectively and the integrated high-strength ball rod ensure an accurate ball positioning. The most distinctive difference between this kind of valve and others is that the online maintenance function can be realized without removing the valve from the pipeline.Feature:API6D DesignOne piece type bodyEmergency sealant injectionCavity pressure self reliefUltrasonic test and Radiographic testLow Fugitive Emission PackingBlow Out Proof Stem DesignLow temperature ball valve?Fire-safe Certified API 607Anti-Static Device铸件上装.0_asm1.pdf
