API 6D Top entry trunnion ball valve introduction
API 6D Top entry trunnion ball valve is trunnion mounted structure,simple and quick to disassemble in the pipeline, convenient and quick to maintain.In the event of API 6D Top entry trunnion ball valve failure in the line that requires repair, instead of removing the top entry ball valve from the line, remove the flange bolts and nuts, remove the cover and stem assembly together from the body, and remove the ball and seat assembly.API 6D Top entry trunnion ball valve Ball and seat can be repaired online.This maintenance of API 6D Top entry trunnion ball valve saves time and keeps production losses to a minimum.

API 6D Top entry trunnion ball valve feature
API 6D Top entry trunnion ball valve body is integral design, not because the stretch our microcosm ring valve using, sphere and valve seat are adopted top entry structure, maintenance and repair the ball valve does not need to be removed from the pipeline valve, API 6D Top entry trunnion ball valve ball and stem can be adopted one-piece, effective solution to the stem and ball processing clearance, to ensure that the sphere of essence to determine the position and stem blow-out proof protection structure.The stem and bonnet seal of API 6D Top entry trunnion ball valve is not an ordinary packing seal, but a packing box combination seal.API 6D Top entry trunnion ball valve Ball and seat can be PTFE, PPL,Delvon,PEEK or metal hard seal upon customer's request.
