The traditional packing flange design has been improved to be of two piece structure,I.E.,Being as a gland flange and gland,the latter contacts the gland with spherical surface,Thus,the gland remains vertical always,and is lined internally with a PTFE bush to prevent the galling against and friction between the stem,which can also reduce the operation troque of the valves.
Based on customers’ requirements,a packing tightening design may be employed to obtain more reliable stem packing seal,which is loaded by bevelling spring.
To prevenet the ball valve from wrong operation,the key lock with 90 deg of open and close positioning pad has been provided,which can be lockable as required.at the stem head,where the lever fixes,a flat is so designed that the valve opens with the lever in parallel to piping,and with the lever right-angled to the piping,the valve is closed,so,it is ensured that the valve indicator of open and close can never make mistake.
