Iivalvu zokulinganisa zeHikelok zibonelela ngeevalvu zokulinganisa ezi-4, ezihlangabezana noxinzelelo olwahlukeneyo, ubushushu, i-Cv kunye noqhagamshelo.
Iivalvu zokulinganisa zeHikelok zibonelela ngolawulo oluchanekileyo lokuhamba kwamanzi kwiindawo ezininzi.
Uxinzelelo oluphezulu lokusebenza kwevalvu yokulinganisa uthotho lwe-MV1 yi-2000 psig (137 bar). I-stem taper yayo yi-1°. Ineepateni ezine ezithe tye, ezi-engile, ezinqamlezileyo neziphindwe kabini, izibambo ezintathu ezigobileyo, ezi-vernier nezinama-slotted.
Uxinzelelo oluphezulu lokusebenza kwevalvu yokulinganisa uthotho lwe-MV2 yi-1000 psig (68.9 bar). I-stem taper yayo yi-3°. Ineepateni ezine ezithe tye, ezi-engile, ezinqamlezileyo neziphindwe kabini, izibambo ezimbini ezigobileyo neziqinileyo.
Uxinzelelo oluphezulu lokusebenza kwevalvu yokulinganisa uthotho lwe-MV3 yi-1000 psig (68.9 bar). I-stem taper yayo yi-5°. Ineepateni ezimbini ezithe tye nezi-engile, iziphatho ezimbini ezigobileyo nezi-vernier.
Uxinzelelo oluphezulu lokusebenza kwevalvu yokulinganisa uthotho lwe-MV4 yi-5000 psig (344 bar). I-stem taper yayo yi-2°. Ineepateni ezimbini ezithe tye kunye ne-engile, esinye isiphatho se-knurled.
IHikelokngomnye wabavelisi abaphambili abaziingcali beevalvu zezixhobo kunye nezixhobo eTshayina.Ukukhethwa nokuvavanywa kwezinto ezisemgangathweni ophezulu, iteknoloji yokucubungula esemgangathweni ophezulu, ulawulo lwenkqubo yemveliso egudileyo kunye nabasebenzi abangochwephesha bemveliso kunye nokuhlolwa bahambisa iimveliso., idala amakhulu eemveliso ezikumgangatho ophezuluiivalvukwayeizixhobo zokufakelwaYeyona ndlela ilungileyo yokuthenga kwakho kwindawo enye, okonga ixesha namandla.
Emva kweminyaka emininzi yemizamo, iHikelok iye yaba ngumthengisi wabathengi abaziwayo abafana neSinopec, PetroChina, CNOOC, SSGC, Siemens, ABB, Emerson, TYCO, Honeywell, Gazprom, Rosneft kunye neGeneral Electric. IHikelok ifumene udumo olukhulu kubathengi ngenxaulawulo lobuchwephesha, iteknoloji evuthiweyo kunye nenkonzo enyanisekileyo.
