IntshayeleloIivalvu zokunceda ezingaphantsi kolwandle zisebenzisa uyilo lwesihlalo esithambileyo ukuze kungene umoya okhuselekileyo kwiigesi xa uxinzelelo lubekwe.
ukusuka kwi-1,500 psi (103 bar) ukuya kwi-20,000 psi (1378 bar). Ubunjineli bezinto kunye neenkqubo zokulawula umgangatho ezingqongqo ziyadibana ukuqinisekisa umgangatho ophezulu, ukuthembeka kunye nobomi benkonzo. Ivalvu nganye imiselwe kwangaphambili kwaye ivalwe ngumzi-mveliso ukuqinisekisa ukusebenza kakuhle kwevalvu.

IimbonakaloIivalvu zokunceda izihlalo ezithambileyoUxinzelelo olusetiweyo: 1500 ukuya kwi-20,000 psig (103 ukuya kwi-1379 bar)Ubunzulu bamanzi obukhulu: 11,500 ft (3505 metres)Ubushushu bokusebenza: 0°F ukuya kuma-250°F (17.8°C ukuya kuma-121°C)Inkonzo yolwelo okanye yegesi. Nika igesi evaliweyo ngebhamuzaUseto loxinzelelo lwenziwa kumzi-mveliso kwaye iivalvu ziphawulwa ngokufanelekileyoXela uxinzelelo olufunekayo kunye ne-odolo ncedaTshixa isigqubuthelo esiqinileyo esinentambo ukuze ugcine uxinzelelo olubekiweyo
Iingeneloiivalvu zesihlalo ezithambileyo zibonelela ngobomi obuphezulu bomjikelo kuneevalvu zokunceda isihlalo zesinyithiUyilo lwesihlalo esithambileyo lubonelela ngokutywinwa okuqinileyo kwamaqamza, ukuvela okuphindaphindwayo, kunye nokuhlaliswa kwakhonaakukho kuvuza
Ezinye iindlelaIimithombo ezintathu zoxinzelelo ezahlukeneyo ozikhethelayoIzinto ezikhethekileyo ezikhethiweyo zenkonzo egqithisileyo
