I-petroleum refinery ibhekisa kwisityalo esivelisa idizili, ipetroli, i-parafini, ioyile yokuthambisa, i-petroleum coke, i-asphalt, kunye ne-ethylene kwiinkqubo ezifana ne-distillation, i-catalysis, i-cracking, i-cracking, kunye ne-hydrorefining ye-oyile ekrwada ekhutshwe kwisakhiwo.
Iivalvu eziveliswa yi-NEWSWY zinokuhlangabezana ngokupheleleyo neevalvu ezahlukeneyo ezifunekayo ngumzi-mveliso wokucoca ukuthintela umlilo, ukuqhuma kunye nezinye iimeko eziyingozi kwaye ziqinisekise ukusebenza ngokukhuselekileyo kwezixhobo.
Kwiiyunithi zokucoca, iiyunithi ezisetyenziswa rhoqo kunye nokukhethwa kweevalvu ezifanayo ezenziwe yi-NEWSWY valve:
Ivalvu enganyangekiyo yeHydrogen sulfide:
Ivalvu yebhola enganyangekiyo nesalfure
Ivalvu yesango enganyangekiyo nesalfure
Ivalve yeBhola yeSitulo seMetal
Ivalvu yePlug yeDBB
Ivalvu yePlug yeTywina lesinyithi
I-Flat Gate Valve
Izixhobo zeCatalytic Valve:
iivalvu zeplagi, iivalvu zokudambisa eziya kwicala elinye, iivalvu zebhabhathane ezinobushushu obuphezulu, iivalvu zebhabhathane ezisebenzisa umoya, iivalvu zesango ezinobushushu obuphezulu, ikakhulu iivalvu ezinganyangekiyo kubushushu obuphezulu.
Iivalvu zemveliso yeHydrogen, iivalvu zeHydrogenation, iivalvu zeyunithi yokulungisa:
ivalvu yebhola ejikelezayo, ivalvu yokulawula, ivalvu yeglobhu yohlobo lwe-Y, ivalvu yebhabhathane ye-hydraulic, ivalvu yoxinzelelo oluphezulu, uxinzelelo luhlala luphezulu kune-1500LB.
Iivalvu zesixhobo sokupheka:
Ivalvu yebhola eneendlela ezimbini, ivalvu yebhola eneendlela ezine, ivalvu yeplagi, ikakhulu isekelwe kwiivalvu zobushushu obuphezulu, izinto ezisetyenzisiweyo ikakhulu yintsimbi ye-chrome-molybdenum. Iivalvu zebhola yetywina enzima yoxinzelelo oluphezulu, zihlala zisuka kwi-1500 LB ukuya kwi-2500 LB.
Iivalvu zeyunithi yokunyibilikisa umoya kunye ne-vacuum:
ivalvu yesango lombane, eyenziwe nge-chrome molybdenum kunye nentsimbi engagqwaliyo
Iivalvu zesixhobo sesalfure:
ivalvu yejakethi ephambili yokwambathisa, ivalvu yesango elinejakethi, ivalvu yebhola enejakethi, ivalvu yeplagi enejakethi, ivalvu yebhabhathane enejakethi.
Iivalvu zesixhobo se-S-zorb:
Ivalvu yebhola yentsimbi eqinileyo, efunekayo ukuze iguge kwaye ishushu kakhulu.
Iivalvu zeyunithi yePolypropylene:
ivalvu yebhola yomoya yentsimbi engatyiwayo
Akukho zivalo zesixhobo ezithile:
ikakhulu ivalvu elawulayo: ivalvu yebhabhathane ephuma emoyeni, ivalvu yebhola ephuma emoyeni, ivalvu yebhola yecandelo lomoya, iivalvu zokulawula iglobhu njalo njalo.
