Muyezo wa valavu wamba: ASME B16.34 flange end, butt welding end ndi threaded end valve

-Valavu ya chipata:

API 600 / ISO 10434 Valavu yachitsulo yolumikizidwa ndi mafuta ndi gasi
Ma valve a zipata zachitsulo a BS 1414 a mafakitale amafuta, petrochemical ndi mafuta oyenga
API 603 150LB valavu yoteteza dzimbiri yoteteza ku flange-end cast gate
Valavu ya chipata chachitsulo cha GB / T 12234 cholumikizira flange ndi chiuno
Valavu ya chipata cha DIN 3352
SHELL SPE 77/103 malinga ndi valavu ya chipata chachitsulo cha ISO10434

-Valavu ya globe:

Ma Valves a Chitsulo a BS 1873 ndi Ma Valves Oyang'anira Chitsulo
valavu ya GB / T 12235 yolumikizidwa ndi flange ndi butt chitsulo chozungulira ndi valavu yowunikira globe
Valavu ya DIN 3356 globe
SHELL SPE 77/103 malinga ndi BS1873 chitsulo globe valve

- Chongani valavu:

Valavu yoyezera zitsulo ya BS 1868
API 594 Wafer ndi Double Flange Check Valve
Valavu yoyesera ya GB / T 12236 yachitsulo
SHELL SPE 77/104 malinga ndi valavu yowunikira zitsulo ya BS1868

-Valavu ya mpira:

Valavu ya mapaipi ya API 6D / ISO 14313
Ma valve a mpira wachitsulo opangidwa ndi flange, ulusi ndi welded a API 608
Ma valve a mpira wachitsulo a ISO 17292 a mafakitale amafuta, petrochemical ndi mafuta oyenga
BS 5351 Chitsulo Mpira Valavu
Valavu ya mpira wachitsulo ya GB / T 12237 flange ndi mbuyo yowotcherera
Valavu ya mpira ya DIN 3357
SHELL SPE 77/100 malinga ndi BS5351 ball valve
SHELL SPE 77/130 malinga ndi ISO14313 flange end ndi butt welding end ball valve.

-Vavu ya gulugufe:

Ma valve a gulugufe a API 609 Wafer, lug ndi double flange
Valavu ya Gulugufe ya MSS SP-67
Valavu ya Gulugufe ya MSS SP-68 Yopanikizika Kwambiri
Ma valve a mpira wachitsulo a ISO 17292 a mafakitale amafuta, petrochemical ndi mafuta oyenga
valavu ya gulugufe yolumikizira ya GB / T 12238 flange ndi wafer
Valavu ya gulugufe ya JB / T 8527 yosindikizira zitsulo
Valavu ya gulugufe yofewa ya SHELL SPE 77/106 yolumikizidwa ndi API608 / EN593 / MSS SP67
SHELL SPE 77/134 malinga ndi API608 / EN593 / MSS SP67 / 68 valavu ya gulugufe yodziwika bwino
