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.

              laser cutting machineÂ
Features:
1.To cater to larger material cutting in co2 metal and non metal cutting industry,this machine adopts large and solid cast steel machine lathe,to make it more capable in material load bearing,at the same time,let the machine operating stable during work.
Â
2.With ball screw transmission on one side of the it,this machine acquires high precision in metal cutting .Special up amd down adjusting laser head ,enables it processing well on uneven metal materials.
Â
3.Imported Japanese servo motor,more powerful and stable compares with traditional china made servo motor ,cooperating with the imported ball screw,this machine get additional more precision and flexibility in cutting result than the ordinary model.
Â
4.This machine can also be customized.
