A:The maximum permissible leakage of the valve with non-metal elastic seals is zero, and that of the ball valve with meal seals is0.1xDNmm3/S. Therefore, acceptable valves with metal seals possibly have slight leakage. So, in the applications where must not be any leakage, especially at the pipeline ends, ball valves with soft seals should be used.
BIf the ball valve with pipe thread connection is connected with the pipe threads on the pipe end, its female thread may be parallel or tapered one, but its male thread must be tapered type. When installing the valve, it is necessary to clamp the hexagonal or octagonal position on the same side as its thread instead of the hexagonal position on the other end of the valve, so as to prevent the valve deforming.
CNominal pressure of brass ball valve is 1.6MPa, 2.5MPa, 4.0MPa, the temperature is -20°C~120°C. When the valve is used for saturated steam. The pressure of the saturated steam should be ≤0.6MPa.
DTo increase the service life of a ball valve, it should be full opened or closed instead of partial opening for throttling purpose, as when it is partially open, the flowing medium will erode the ball and sealing
surface and thus affect the sealing performance of the valve
