Ball
valves are usually used for shutting off or connecting the medium flow.
The
maximum permissible leakage of the valve with non-metal elastic seals is zero,
and that of the Ball Valve with meal seals is 0.1xDNmm3/s.
Therefore, acceptable valves with metal seals possibly have slight
leakage. Hence, in the applications where there must not be any leakage,especially at the pipeline
ends, ball valves with soft seals should be used.
Nominal pressure of brass
ball valve is 1.6MPa, 2.0MPa and 2.5MPa. When the ball valve is used for
saturated steam, the pressure of the saturated steam should be ≤0.6MPa.used.
