8.VALVE STRUCTURE:
The valve adopts three-piece side-mount forge welding structure
and the sphere is supported by the supporting plate built inside
the valve body, which eliminates the excessive torque caused
by the huge loading seal when the inlet pressure pushes against
the sphere. The surface finish of the sphere reaches the mirror
surface; the use of metallic bushing lining with good lubrication
also ensures small open/close torque even under maximal
operating pressure.
