Iivalvu ezichanekileyo, imibhobho kunye nezixhobo zibalulekile ekusebenzeni ngempumelelo kwezibonelelo zokuvelisa umbane. Esi sixhobo sibandakanya iimveliso ezinoyilo olunemisebenzi emininzi ukuseka uqhagamshelo olusebenzayo kunye neendlela zokutywina, kunye nemfezeko yoqhagamshelo olungcono ukuqinisekisa ukusebenza ngokukhuselekileyo kwemizi-mveliso yamandla ashushu, amaziko ombane enyukliya kunye namaziko ombane ahlaziyekayo. Xa bekhuthaza iimveliso zabo, abavelisi bathi iindleko zokufakela ziphantsi, ukhuseleko kunye nokusebenza kakuhle kuphezulu, kwaye ixesha lokunciphisa elicwangcisiweyo nelingalindelekanga liyancipha. Ezinye ivalve yeplanti yamandla ekhokelayo, umbhobho kunye nabavelisi abafanelekileyo kunye neenkampani zenkonzo zineempawu zazo apha.
Ekuqaleni kwalo nyaka, i-Boldrocchi ivavanye ngempumelelo isidambisi-manzi sayo esitsha se-7m nge-7m shunt kwiiinjini zegesi. Ivalve yokuphambukisa yivalve eneendlela ezintathu ezinokukhuphela irhasi yokukhupha i-iturbine yerhasi emoyeni ngetshimini edlulayo okanye kwijenereyitha yokubuyisa ubushushu. I-damper inomthamo ophezulu kakhulu kwaye idlula umgangatho ngokwemiqathango yokutywinwa kwejometri, ukutywinwa koxinzelelo kunye nexesha lokuvala, ngelixa unciphisa ukugcinwa kunye nokwenza lula ukuthutha kunye nokudibanisa. Le diverter entsha iphinda ivumele utshintsho olukhawulezayo ukusuka kwinkqubo yomjikelezo omnye ukuya kwinkqubo yomjikelezo odibeneyo. Yenzelwe ukumelana namaqondo obushushu ukuya kuthi ga kwi-700C (1,300F), ukungcangcazela kunye nesiphithiphithi segesi, kunye nokunyuka kokunxiba kwecandelo. I-diverter ixhotyiswe ngenkqubo yomoya, enokwenza ukuba umoya we-exhaust gas ufikelele kwi-100% (itywinwe ngokupheleleyo). Uxinzelelo lwetywina lomoya likhulu kune +500 millimeters yoluhlu lwamanzi (mm wc), kwaye abavelisi bezixhobo zokuqala bahlala befuna +50 mm wc. I-shunt ixhotyiswe nge-actuator ye-hydraulic. Ngokweemfuno zabathengi, ixesha eliqhelekileyo lokusebenza lingaphantsi kwemizuzwana ye-60, kwaye ixesha lokuvala likaxakeka lingaphantsi kwemizuzwana ye-20. Nangona kunjalo, i-shunt iyilwe kwaye yenziwe ukufumana ixesha elifutshane lokuqhuba. I-Boldrocchi yenzelwe le diverter ukuququzelela ukuthutha kunye nendibano. I-splitter inokudityaniswa kwangaphambili ibe ngamaqhekeza amaninzi, okanye inokuhanjiswa ngokupheleleyo (kwinxalenye enye). I-Boldrocchi yenzelwe le ngqungquthela, enokuthi ifakwe ngokulula phantsi kombhobho wokukhupha umjikelo omnye endaweni yengqiniba ekhoyo. Boldrocchi, Biassono, Italy
I-Spirax Sarco ibonelela ngeemveliso kunye neenkonzo zezisombululo zamandla ashushu. Ivalve yokulawula imodyuli ye-Spira-trol iye yagunyaziswa kwangaphambili kwisicelo ngaphambi kokuba ihambe kwifektri, ivumela ukufakwa ngokukhawuleza "kweplagi kunye nokudlala". Idizayini yemodyuli yeSpira-trol, enesihlalo sevalvu yokutshintsha ngokukhawuleza “i-clamp-in-place”, ithetha ukuba uxanduva lwayo lunokutshintshwa ukuze luhambelane nokutshintsha kweemeko zasefektri endaweni yokutshintsha ivalve yonke. Isitulo sevalve esizilungelelanisayo sisenza lula ukugcinwa, ngoko ke akukho zixhobo zikhethekileyo zifunekayo, kwaye akukho mfuneko yokukhupha ivalve kumbhobho. Xa kuthelekiswa ne-screw-in isihlalo soyilo, esihlala sibambekile endaweni, oku kuphumeza ukugcinwa kweendleko ezinkulu, kufuna ukuba ivalve ikhutshwe, okukhokelela ekuvaleni kwezityalo ixesha elide. Iivalve ze-Spira-trol eziqhutywa ngombane kunye ne-pneumatically ukusuka kwi-1/2 intshi ukuya kwi-intshi ezi-4 ziyafumaneka, ukuya kwi-flange ye-ANSI 150.
