Paralan ning pamamili keng globe valve—TWS Valve

Deng globe valves maralas lang gagamitan at dakal la uri. Deng peka-uri ilapin deng bellows globe valves, flange globe valves, internal thread globe valves, stainless steel globe valves, DC globe valves, needle globe valves, Y-shaped globe valves, angle globe valves, atbp. type globe valve, heat preservation globe valve, cast steel globe valve, forge steel globe valve; nung makananu yang mamili ing uri na importanti ya, kailangan yang mamili agpang keng katangian ning medium, temperatura, pressure ampo ing kundisyun ning obra. Deng partikular a tuntunan king pamili ila pin deng makatuki:

1. Ing pneumatic globe valve dapat yang mapili keng pipeline o device na matas a temperatura ampo matas a pressure medium. Antimo reng matas a temperatura ampo matas a pressure a pipeline kareng thermal power plants ampo petrochemical systems;

2. Ing direct-flow globe valve dapat gamitan ya keng pipeline nung nukarin ali la mahigpit deng convection resistance requirements;

3. Needle valve, instrument valve, sampling valve, pressure gauge valve, atbp. malyari lang gamitan para keng malating pneumatic globe valve;

4. Atin yang pamag-adjust keng danum o pamag-adjust keng pressure, pero ali ya matas ing requirements para keng adjustment accuracy, ampo ing diameter ning pipeline medyu malati ya. Alimbawa, keng pipeline na ating nominal diameter a ≤50mm, mas masanting ing gamitan me ing pneumatic stop valve ampo ing electric control valve;

5. Para keng madaling-solidify crystallization medium, mamili kang heat preservation shut-off valve;

6. Para kareng ultra-high pressure a kapaligiran, dapat lang pilinan deng forged globe valves;

7. Deng malating pataba ampo deng mangaragul a pataba keng synthetic industrial production dapat mamili lang high pressure angle globe valve o high pressure angle throttle valve a maki nominal pressure PN160 nominal pressure 16MPa o PN320 nominal pressure 32MPa;

8. Ing desiliconization workshop ampo reng pipelines a prone keng coking keng alumina Bayer process, madali yang mamili direct-flow globe valve o direct-flow throttle valve a ating separate valve body, removable valve seat, ampo cemented carbide sealing pair;

9. keng proyektung suplay ning danum ampo pamaninit keng urban construction, mas malati ya ing nominal a dalan, ampo ing pneumatic shut-off valve, balance valve o plunger valve malyari yang pilinan, alimbawa, ing nominal a dalan mas ditak ya keng 150mm.

10. Mas masanting ing mamili kang imported bellows globe valve para keng hmatas a temperatura steam ampo makalasun a media.

11. Para keng acid-base globe valve, pilinan me ing stainless steel globe valve o fluorine-lined globe valve.
