Ivalvu yebhola iphuhliswe kwivalvu yeplagi, inesenzo esifanayo sokuphakamisa ukujikeleza kwama-degree angama-90. Ivalvu yebhola ingavalwa ngokuqinileyo ngokujikeleza kwama-degree angama-90 kuphela kunye ne-torque encinci. Umngxuma wangaphakathi olinganayo ngokupheleleyo wevalvu ubonelela ngomjelo wokuhamba ngokuthe tye ongenakuphikiswa kangako kwi-medium.

Eyona nto iphambili kwivalvu yebhola yisakhiwo sayo esincinci, kulula ukuyisebenzisa nokugcina icocekile, ifanelekile kwiindawo zokusebenza ngokubanzi ezifana namanzi, isinyibilikisi, iasidi kunye negesi yendalo, kwaye ifanelekile nakwiindawo zokusebenza ezinzima, ezifana neoksijini, ihydrogen peroxide, i-methane kunye ne-ethylene. Umzimba wevalvu yebhola unokuba yi-integral okanye udityaniswe.

Inxalenye yokuvala yevalvu yebhola yisphere, uhlobo lwevalvu apho isphere ijikeleza khona umgca osembindini womzimba wevalvu ukuze kuvuleke kwaye kuvalwe. Ivalvu yebhola isetyenziselwa kakhulu ukusika, ukusasaza kunye nokutshintsha indlela yokuhamba kwesixhobo esikwipayipi. Ivalvu yebhola luhlobo olutsha lwevalvu oluye lwasetyenziswa kakhulu kwiminyaka yakutshanje. Inezibonelelo ezininzi, ezi zilandelayo:

Inokumelana okuphantsi kokuhamba kwamanzi (ngokwenene yi-0);
Ngenxa yokuba ayizukubambeka ngexesha lomsebenzi (xa kungekho lubricant), ingasetyenziswa kwi-corrosive media kunye ne-low boiling point liquids;
Kwinqanaba eliphezulu loxinzelelo kunye nobushushu, inokufikelela ekutywinweni okupheleleyo;
Ingenza ukuvulwa nokuvalwa ngokukhawuleza, kwaye ixesha lokuvulwa nokuvalwa kwezinye izakhiwo yi-0.05 ~ 0.1s kuphela ukuqinisekisa ukuba ingasetyenziswa kwinkqubo yokuzenzekelayo yebhentshi yovavanyo. Xa ivula kwaye ivala ivalvu ngokukhawuleza, akukho shock isebenza;
Ukuvalwa okungqukuva kunokubekwa ngokuzenzekelayo kwindawo yomda;
Xa ivuliwe ngokupheleleyo kwaye ivaliwe ngokupheleleyo, umphezulu wokutywina webhola kunye nesihlalo sevalvu ziyahlukaniswa kwi-medium, ngoko ke i-medium edlula kwivalvu ngesantya esiphezulu ayizukubangela ukukhukuliseka komphezulu wokutywina;
Ngesakhiwo esincinci kunye nobunzima obuphantsi, ingathathwa njengesakhiwo sevalvu esifanelekileyo kwiinkqubo zemidiya ye-cryogenic;
Umzimba wevalvu ulingana, ingakumbi isakhiwo somzimba wevalvu edibeneyo, esinokumelana noxinzelelo oluvela emthonjeni wepayipi;
Isiqwenga sokuvala sinokumelana nomahluko ophezulu woxinzelelo xa sivaliwe;

INortech ngomnye wabavelisi beevalvu zoshishino abaphambili eTshayina abanesiqinisekiso somgangatho se-ISO9001.
