A351 CF8M Hlau -Seated Floating Ball Valve Nta:
Sab saum toj -Tier Corrosion Resistance:Lub 316 SS substrate ua ke nrog Molybdenum muab ntev - lub sij hawm tsis kam mus rau nruab nrab -concentration sulfuric acid, organic acids, ntsev tsuag, thiab chloride daws.
"Hard-on-Hard" Shear Design:HVOF Tungsten Carbide txheej muaj cov hardness siab heev thiab ceev. Raws li lub pob rotates, nws yooj yim txiav los ntawm cov muaju los yog deposits ntawm lub sealing nto yam tsis muaj khawb.
Dynamic Thermal Compensation:Lub caij nplooj ntoos hlav Belleville-loaded lub rooj tsim tiv thaiv kev ntes lossis xau los ntawm cov khoom siv nthuav dav thiab kev cog lus thaum lub sijhawm kub hloov pauv, ua kom lub zog ua haujlwm tas li.
Ntev & Kev Nyab Xeeb:Tag nrho - hlau tsim ua rau lub valve intrinsically tua hluav taws- nyab xeeb (API 607). Hauv kev tshaj xov xwm abrasive, nws lub neej kev pabcuam feem ntau yog ntau tshaj 5 npaug ntawm cov mos- rooj li qub.
