I-DIN EN 13709 1.4308 ivalvu yeglobhu evaliwe yensimbi engagqwali imelela ikhambi elifanele izimboni ezidinga imishini yokulawula ukugeleza ephephile, ethembekile, neyobungani nemvelo. Ngokuhlanganisa ukwakhiwa kwensimbi engagqwali okuhlala isikhathi eside nobuchwepheshe obuthuthukisiwe bokuvala i-bellows, ivalvu inikeza ukusebenza okumangalisayo kokuvala futhi iqeda cishe izingozi zokuvuza kwesiqu.​ Ukuhambisana kwayo nezindinganiso zomhlaba wonke, ukumelana nokugqwala kanye nokushisa, izidingo zokugcinwa eziphansi, kanye nokuphila isikhathi eside kokusebenza kwenza kube ukukhetha okuthandwayo kuzo zonke izinhlelo zomusi, izitshalo zamakhemikhali, izikhungo ze-petrochemical, kanye nezinhlelo zokusebenza ezahlukahlukene zezimboni. Njengoba izimboni zanamuhla ziqhubeka nokubeka phambili ukuphepha kanye nokusimama, amavalvu eglobhu avaliwe e-bellows azohlala eyingxenye ebalulekile ezinhlelweni zenqubo ebalulekile.

I-EN 13709 GS-C25 Flange End Bellows Evaliwe I-Globe Valve iyivalvu yezimboni esebenza kahle kakhulu esetshenziswa kabanzi ezinhlelweni zenqubo ebalulekile lapho akukho ukuvuza, ukulawulwa kokugeleza okunembile, kanye nezindinganiso zokuphepha eziphezulu kuyadingeka. Yakhelwe ngokwezinga laseYurophu I-EN 13709, le valve ihlanganisa umzimba wensimbi yekhabhoni eqinile (izinto ze-GS-C25), ukuxhumeka kokuphela okune-flange, kanye nohlelo lokuvala olususa izingozi zokuvuza kwesiqu. Ivame ukusetshenziswa ezimbonini ezifana nokucubungula amakhemikhali, izitshalo ze-petrochemical, izinhlelo zomusi, ukukhiqizwa kwamandla, izindawo zokuhluza, kanye nokuthuthwa koketshezi oluhlanzekile kakhulu.

I-API 623 Insimbi Ebunjiweyo ye-ASTM A216 WCB Flange End Bellows Evaliweyo Ye-Globe Valve iyivalvu yezimboni eklanywe kahle kakhulu eyenzelwe izinhlelo zokusebenza zokulawula ukugeleza okubalulekile lapho akukho ukuvuza, ukuthembeka okuphezulu, kanye nokuhambisana nezindinganiso zemboni kaphethiloli zibalulekile. Isetshenziswa kabanzi embonini kawoyela negesi, i-petrochemical, ukukhiqizwa kukagesi, kanye nokucubungula amakhemikhali, le valve ihlanganisa izici eziqinile zama-globe valves nobuchwepheshe obuthuthukisiwe bokuvala ama-bellows.

I-DIN EN Bellows Sealed Globe Valve iyisici esibalulekile ezinhlelweni zezimboni zanamuhla, enikeza amakhono okuvala athuthukisiwe, ukuqina, kanye nokulawula ukugeleza okunembile. Ukwakheka kwayo okuqinile, ukuhambisana nezindinganiso zomhlaba wonke, kanye nezidingo zokunakekelwa ezincishisiwe kwenza kube ukukhetha okuhle kwezimboni ezifana nokukhiqizwa kukagesi, ukucubungula amakhemikhali, uwoyela negesi, kanye nokwelashwa kwamanzi. Ngokuhlanganisa ukwakheka kwama-globe valve okuvivinywe isikhathi eside kanye nendlela entsha yokuvala ama-bellow, la ma-valve ahlinzeka ngokusebenza okuphezulu kanye nokuthembeka, okufaka isandla ekusebenzeni kahle kanye nokuphepha kwemisebenzi yezimboni. Uma ukhetha i-valve yokusetshenziswa koketshezi oluphezulu, lokushisa okuphezulu, noma oluyingozi, i-DIN EN Bellows Sealed Globe Valve iyisinqumo esihle kakhulu sokuqinisekisa ukusebenza kwesikhathi eside, okungenawo amanzi.

I-GS-C25 Cast Steel DIN Bellows Sealed Globe Valve, ikakhulukazi uhlobo lwe-angle, imelela ingxenye ebalulekile esetshenziswa ezinhlelweni ezahlukene zezimboni ukulawula nokulawula ukugeleza koketshezi, njengoketshezi namagesi. Yakhiwe ngokwezincazelo eziqinile, lolu hlobo lwe-valve lwenzelwe ukunikeza ukusebenza okuthembekile ngaphansi kwezimo zokucindezela okuphezulu kanye nokushisa okuphezulu. Lesi sihloko sinikeza ukuhlolwa okuningiliziwe komklamo wayo, izinhlelo zokusebenza, izinzuzo, kanye nezici zobuchwepheshe. Uhlobo lwe-GS-C25 Cast Steel DIN Bellows Sealed Globe Valve Angle luyi-valve esebenza kahle kakhulu eyenzelwe ukunikeza ukuqina, ukulawula okunembile, kanye nokusebenza okuvikela ukuvuza ezicelweni zezimboni ezidinga kakhulu. Ngokwakhiwa kwayo kwensimbi ehlanganisiwe, ubuchwepheshe be-bellows seal, kanye nokuhambisana nezindinganiso ze-DIN, kuyisinqumo esihle kakhulu ezimbonini ezifana nokucubungula amakhemikhali, ukukhiqizwa kwamandla, kanye namafutha negesi. Ngokuhlanganisa umklamo we-angle osebenzisa isikhala kahle nezici zokuvala ezithuthukisiwe, i-valve ye-GS-C25 iqinisekisa ukusebenza okuthembekile nokuphephile ngisho nasezindaweni eziyinselele kakhulu.

I-DIN Stainless Steel CF8 Bellows Sealed Globe Valve PN16 iyi-valve yokuhlukanisa enokwethenjelwa kakhulu eyenzelwe izinhlelo zokusebenza lapho kungekho ukuvuza emoyeni, ukulawula ukugeleza okunembile, kanye nokuphila isikhathi eside kubalulekile. Le valve, eyenziwe ngokuhambisana namazinga e-DIN futhi ilinganiswe ngesigaba sokucindezela se-PN16, isetshenziswa kabanzi ekucubungulweni kwamakhemikhali, kwezemithi, ezitshalweni zikagesi, ezinhlelweni ezisizayo zikawoyela negesi, ekudleni naseziphuzweni, nakwezinye izinsizakalo zezimboni ezibandakanya izinto ezibolayo noma eziyingozi.
