Amavalvu alungile, amapayipi kanye nezinto ezifakwayo zibalulekile ekusebenzeni ngempumelelo kwezinsiza zokuphehla ugesi. Izinto zokusebenza zibandakanya imikhiqizo enemiklamo eminingi yokusungula izindlela ezisebenzayo zokuxhuma nezindlela zokuvala, kanye nobuqotho bokuxhumana obungcono ukuze kuqinisekiswe ukusebenza okuphephile kwezitshalo eziphehla amandla ashisayo, izimboni zamandla enuzi kanye nezindawo zokuphehla amandla avuselelekayo. Lapho bekhangisa imikhiqizo yabo, abakhiqizi bathi izindleko zokuyifaka ziphansi, ukuphepha nokusebenza kahle kuphezulu, futhi isikhathi sokuphumula esihleliwe nesingahleliwe siyancishiswa. Amanye ama-valve eplanti yamandla ahamba phambili, abakhiqizi bepayipi nabafakayo kanye nezinkampani zesevisi banezici zabo lapha.
Ngasekuqaleni kwalo nyaka, i-Boldrocchi ihlole ngempumelelo imishini yayo entsha engu-7m by 7m shunt damper ukuthola izinjini zegesi. I-diverter valve iyi-valve enezinhlangothi ezintathu engakhiphela igesi yokukhipha i-turbine yegesi emkhathini ngoshimula odlulayo noma ingene ejeneretha yesitimu sokubuyisa ukushisa. I-damper inomthamo omkhulu kakhulu futhi idlula izinga ngokubekwa uphawu kwejometri, ukucindezela kokuvala kanye nesikhathi sokuvala, kuyilapho kunciphisa ukulungiswa nokwenza lula ukuthutha nokuhlanganisa. Le diverter entsha iphinde ivumele ukuguqulwa okusheshayo kusuka ohlelweni olulodwa lomjikelezo kuya ohlelweni lomjikelezo ohlangene. Idizayinelwe ukumelana namazinga okushisa afika ku-700C (1,300F), ukudlidliza kanye nesiphithiphithi segesi, kanye nokwenyuka kokugqoka kwezingxenye. I-diverter ifakwe uhlelo lwe-airtight, olungenza ukuthi i-airtightness ye-exhaust gas ifinyelele ku-100% (ivalwe ngokugcwele). Umfutho we-air seal mkhulu kuno-+500 millimeters wekholomu yamanzi (mm wc), futhi abakhiqizi bemishini yoqobo ngokuvamile badinga u-+50 mm wc. I-shunt ifakwe i-hydraulic actuator. Ngokwezidingo zamakhasimende, isikhathi esijwayelekile sokusebenza singaphansi kwamasekhondi angu-60, kanti isikhathi sokuvala ucingo esiphuthumayo singaphansi kwamasekhondi angu-20. Nokho, i-shunt yakhelwe futhi yakhiwe ukuze ithole isikhathi esifushane sokushayela. I-Boldrocchi idizayine le-diverter ukuze kube lula ezokuthutha nokuhlanganisa. I-splitter ingahlanganiswa kusengaphambili ibe yizicucu eziningana, noma ingalethwa ihlanganiswe ngokugcwele (ngengxenye eyodwa). I-Boldrocchi iklame lesi sihlukanisi, esingafakwa kalula ngaphansi kwepayipi le-exhaust eliwumjikelezo owodwa esikhundleni sendololwane ekhona. Boldrocchi, Biassono, Italy
I-Spirax Sarco ihlinzeka ngemikhiqizo namasevisi ezixazululo zamandla ashisayo. I-Spira-trol modular control valve iye yagunyazwa kusengaphambili ukuthi ifakwe ngaphambi kokuphuma efekthri, okuvumela ukufakwa okusheshayo kwe-“plug and play”. Idizayini eyimojula yeSpira-trol, enesihlalo sevalvu esishintsha ngokushesha “i-clamp-in-place”, isho ukuthi izibopho zayo zingashintshwa ukuze zivumelane nezimo zefekthri ezishintshayo esikhundleni sokuvala yonke ivalvu. Isihlalo se-valve esiziqondanisa endaweni siphinde senza ukunakekelwa kube lula, ngakho-ke awekho amathuluzi akhethekile adingekayo, futhi asikho isidingo sokukhipha i-valve epayipini. Uma kuqhathaniswa nomklamo wesihlalo esiyisikulufu, esivame ukunamathela endaweni yawo, lokhu kufeza ukonga okukhulu kwezindleko, okudinga ukuba ivalvu ihlakazwe, okuholela ekuvaleni kwezitshalo isikhathi eside. Amavalvu kagesi kanye ne-pneumatically Spira-trol asukela ku-1/2 intshi kuya ku-4 amayintshi ayatholakala, kuze kufike enguqulweni ye-flange ANSI 150. Ngochungechunge oluphelele lwe-Spira-trol olunganwetshwa lube amayintshi angu-8 kanye nobubanzi bengcindezi ye-ANSI 600, i-Spirax Sarco inganikeza izixazululo zokulawula ezisukela ekushiseni, ukungena komoya kanye nesimo somoya, inqubo namandla kuya kuzicelo zesevisi ezifunayo.

I-Clark Valve imemezele ukuthi idizayini yayo ye-valve yesango lokuphathelene isithole isitifiketi se-API 641, okuyivalvu yokulawula yokuqala ezoqinisekiswa ngokusebenza okuphansi kwe-emissions ephansi. Izinga le-API 641 lisebenza kuzo zonke izinto zokuvala isiqu futhi lidinga ukuvuza okuqinile okuphezulu okuvumelekile kwezingxenye eziyi-100 ngesigidi (ppmv). Izinga lokuhlola le-API lidinga ukuthi i-valve ingene emijikelezweni engu-610 ngaphansi kokuguquguquka okukhulu kwezinga lokushisa ukuze ihlole ukusebenza kokukhiphayo phakathi nomjikelezo wempilo osheshisiwe. Ukukhishwa okuphunyukayo kwemiklamo yama-valve yendabuko ezindaweni zezimboni kuyimbangela eyinhloko yokungcoliswa komoya, futhi umklamo oyingqayizivele wamavalvu wamasango uhlinzeka ngokuvaleka okuhle kakhulu esiqwini se-valve, ngaleyo ndlela kuncishiswe lokhu kukhishwa. I-Yarmouth Research and Technology yenza izivivinyo ezizimele ku-valve yesango elinelungelo lobunikazi futhi yafakazela ukuthi i-valve iphumelele ukuhlolwa, futhi ukuvuza kwakungaphansi kuka-20 ppmv, ngaphansi kakhulu komkhawulo we-100 ppmv. Idizayini eyingqayizivele yevalvu yembulunga isivele iyivalvu yokulawula engcono kunazo zonke emhlabeni, futhi iyivalvu yokulawula evumelana kakhulu nemvelo eyake yaqinisekiswa.
