Steel fixed ball floating seat, soft \hard two-stage sealing valve, the primary seal for the metal seal, secondary seal for the non-metallic seal; secondary seal VITON-AED, DEVLON, PEEK and all-metal seals, etc. The ball using the valve body built into the structure of the bearer plate fixed valve fire test according to the provisions of the QAPI607 and BS6755 antistatic, with the valve stem to prevent the blowout function.

Cylinder body group welding form three bodies through two symmetrical longitudinal weld group welding into or two bodies through a longitudinal weld group welding into. Cylinder valve body structure manufacturing process is relatively simple, easy to assemble and locate, billet manufacturing required mold is simple, and easy to use the support plate on the ball to fix, easy to install the stem part, suitable for large Caliber all-welded ball valves.
