Stop
valve is usually used for or connecting the medium flow and is not recommended
for throttling.
The
maximum permissible leakage of the Stop Valve with non-metal elastic seals is
zero, and that of the stop valve with meal seals is 0.1xDNmm3/s. Therefore,
acceptable stop valves with metal seals possibly have slight leakage. Hence, in
the applications where there must not be any leakage,especially at the pipeline ends,stop valves with soft seals should be
used,and shutoff
valves with metal seals should not be used.
Nominal
Pressure of Brass Stop Valve is 1.6MPa. Medium temperature for metal seal is
-20℃~150℃, and medium temperature for non-metal
elastic seal is -20℃~120℃. When the stop valve is used for
saturated steam, the pressure of the saturated steam should be ≤0.6MPa.
