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-valve ye-globe yensimbi engagqwali esebenza ngesandla ye-API iyisisombululo esithembekile nesiguquguqukayo sokulawula ukugeleza kwezimboni kanye nezicelo zokuvala. Ukwakhiwa kwayo kwensimbi engagqwali kunikeza ukumelana okuhle kakhulu kokugqwala, kuyilapho ukwakheka okujwayelekile kwe-API kuqinisekisa ukuphepha, ukuqina, kanye nokusebenza okuthembekile ngaphansi kwezimo zokusebenza ezidinga kakhulu. Ngezinzuzo ezifana nekhono lokugoqa eliqondile, ukusebenza okuqinile kokuvala, ukulungiswa okulula, kanye nokuphila isikhathi eside kwenkonzo, ama-globe ensimbi engagqwali ahlala engenye yama-valve abaluleke kakhulu ezimbonini kufaka phakathi uwoyela negesi, i-petrochemical, ukukhiqizwa kwamandla, ubunjiniyela basolwandle, kanye nokwelashwa kwamanzi.

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-valve ye-API 602 flange end compact steel globe imele i- isixazululo esisebenza kahle kakhulu sezicelo zezimboni ezifuna kakhulu. Ukwakhiwa kwayo okubumbene, ukuvala okuthembekile, kanye namakhono okulawula ukugeleza okunembile kwenza kube ukukhetha okuthandwayo ezinhlelweni ezibalulekile. Yakhelwe ukuhlangabezana nezindinganiso eziqinile zemboni, inikeza ukuqina, ukuphepha, kanye nokusebenza kahle ezindaweni ezinomfutho ophezulu. Konjiniyela kanye nochwepheshe bokuthenga, ukuqonda izici zayo zokuklama kanye nezinzuzo zokusebenza kubalulekile ekukhetheni ivalvu efanele yokusebenza isikhathi eside, okungenazinkinga.

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-valve yomhlaba ye-DIN EN 13709 flange end angle type without bellows iyi-valve yokunyakaza eqondile eyenzelwe ukulawula, ukuphotha, noma ukuhlukanisa ukugeleza koketshezi emapayipini. Yakhiwe ngokwezindinganiso ze-DIN (Deutsches Institut für Normung), le valve ineziphetho ezi-flanged zokuxhuma okuqinile okunamabholidi kanye nomzimba wephethini ye-angle oshintsha indlela yokugeleza ngama-degree angu-90. Ngokungafani nezinhlobo ezivaliwe ngamabholi, isebenzisa ilungiselelo lendabuko lokupakisha isiqu ukuvimbela ukuvuza okuzungeze isiqu. Lawa ma-valve asetshenziswa kabanzi ezinhlelweni zezimboni ezifana nezitshalo zikagesi, izikhungo zokucubungula amakhemikhali, ukufakwa kukawoyela negesi, izinhlelo ze-HVAC, izitshalo zokwelashwa kwamanzi, kanye namanethiwekhi okusabalalisa umusi.

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.
