Njengoko igama lisitsho, i6 intshi yevalve yesangoinobubanzi obuyi-intshi ezi-6. Ngokwemigangatho yamazwe ngamazwe, i-intshi eyi-1 ilingana no-25.4 mm, ngoko i-intshi ezi-6 zilingana no-152.4 mm. Nangona kunjalo, kwiimveliso zokwenyani zevalvu, siqhele ukusebenzisa i-diameter yegama (DN) ukubonisa ubungakanani bevalve. Idayamitha ye-intshi ye-6-intshi ngokubanzi yi-150 mm. Imigangatho yethu yoyilo lwevalvu yesango ibandakanya i-API 600 kunye ne-API 6D. Nceda uqhagamshelane nathi ngolwazi oluthile lobungakanani kunyeixabiso levalve yesangos. Inkampani yeValve ye-NSW iya kubonelela ngeekowuti zevalvu kunye nemizobo yevalvu ngaphandle kwentlawulo.
Ukongeza kwi-diameter kunye nobubanzi bangaphandle, ukunyanzeliswa koxinzelelo lwe-valve yinto ebalulekileyo yokuqwalasela xa ukhetha. Ubungakanani boxinzelelo oluphezulu lwe-valve ye-6-intshi ngokuqhelekileyo lungaphantsi kwe-2,500 pounds, oku kuthetha ukuba phantsi kweemeko eziqhelekileyo zokusebenza, uxinzelelo oluphezulu olunokumelana nalo akufanele ludlule lo mda. Ngaphandle koko, imiba yokhuseleko efana nomonakalo wevalvu okanye ukuvuza kunokwenzeka.
Uxinzelelo oluncinci lweevalvu zesango eziveliswe yiNSW Valve Company yiClass 150LB, iClass 300LB, Class 600LB, Class 1500LB, Class 2500LB, kwaye sinokwenza ngokwezifiso ezinye iingcinezelo.
Izinto eziqhelekileyo zeevalve zesango ziyi-carbon steel, insimbi engenasici, i-duplex insimbi engenasici, i-aluminium yobhedu kunye nezinye iintsimbi ezikhethekileyo ze-alloy.
I-NSW ngumthomboI-Gate Valve Factory. Ivalve yethu ye-intshi ye-intshi ezi-6 kunye nobunye ubungakanani beevalvu zesango banamaxabiso akhuphisanayo, anokukunceda ukuba ungene ngokukhawuleza kwimarike yevalvu. Ngelo xesha, siqinisekisa kwakhona ukuba iivalve zethu zesango zihambelana ngokupheleleyo nemigangatho yamazwe ngamazwe ye-API 600 kunye ne-API 6D.
Iivalvu zesango eziyi-intshi ezi-6 zisetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo zemibhobho yoshishino ukulawula ukuhamba kolwelo. Ngenxa yomgangatho ophakathi kunye nokumelana noxinzelelo, iivalvu ze-intshi ezi-6 zifanelekile kumajelo osasazo olwelo jikelele njengamanzi, umphunga, ioyile, kwaye ingasetyenziselwa ezinye izinto ezidliwayo okanye ubushushu obuphezulu kunye noxinzelelo oluphezulu lwemidiya ekhethekileyo. Xa ukhetha, uhlobo lwevalve efanelekileyo kunye nezinto eziphathekayo kufuneka zikhethwe ngokwemiqathango yokusetyenziswa kwangempela kunye neempawu eziphakathi.
Xa ukhetha i-intshi ye-intshi ye-valve yesango, ukongeza ekuqwalaseleni iiparameters ezisisiseko ezifana ne-caliber, i-diameter yangaphandle kunye nokumelana noxinzelelo, kufuneka uhlawule ingqalelo kwizinto ezifana nohlobo lwesakhiwo sevalve, ukusebenza kokutywinwa, indlela yokusebenza, kunye nomvelisi. Iimveliso ze-valve ezikumgangatho ophezulu azinayo nje ukusebenza kakuhle kunye nobomi benkonzo, kodwa zibonelela ngeziqinisekiso ezizinzile nezithembekileyo kwimveliso yoshishino. Ngoko ke, kucetyiswa ukuba xa ukhetha iivalve, unike kuqala kwiimpawu eziziwayo kunye nabavelisi abanegama elihle. Iivalvu ze-NSW sele zisebenza ngokukhethekileyo kwimveliso kunye nokuthunyelwa kwamanye amazwe iivalvu zesango iminyaka engaphezu kwama-20 kwaye ngumboneleli wevalvu yesango onokumthemba.
