Ukujongana nokusilela kunye noLondolozo lweIValve yebhabhathane ePhakathi kuQhagamshelwano lweFlange laseTshayina
Kwiinkqubo zemveliso yemizi-mveliso,izivalo butterfly centerline sisixhobo esiqhelekileyo sokulawula ukuhamba kunye noxinzelelo lwemidiya ye-fluid. Xa i-valve ye-butterfly ye-centerline ixhunywe kwi-flange ukungasebenzi kakuhle, ukugcinwa kuyadingeka. Eli nqaku liza kwazisa iindlela zokuphatha iziphene kunye nokugcinwa kweevalve zebhabhathane kumgca ophakathi wokudibanisa i-flange e-China.
