I-NORTECHis enye yezona China ziphambiliIvalvu yeGlobe Umenzi kunye noMboneleli.

Ivalvu yokuvala ibhekisa kwigama elithi isango apho isiqwenga sokuvala (i-wide flap) sihamba khona kumgca osembindini wesihlalo sevalvu. Ngokwale ndlela yokuhamba kwediski yevalvu, utshintsho lwesango lesihlalo sevalvu luhambelana nokubetha kwevalvu. Ekubeni ukubetheka kokuvula okanye kokuvala kwesiqu sevalvu solu hlobo lwevalvu kufutshane,
Ngaphezu koko, inomsebenzi wokunqunyulwa othembekileyo kakhulu, kwaye ngenxa yokuba utshintsho lwesango lesihlalo sevalvu luhambelana nokubetha kwediski yevalvu, ifanelekile kakhulu ukulungiswa kokuhamba kwamanzi. Ke ngoko, olu hlobo lwevalvu yokuvala lufanelekile kakhulu ukusetyenziswa njengesiciko sokuvala okanye sokulungisa kunye nokuqhobosha.
Eyona nzuzo icacileyo yevalvu yeglobe kukuba kwinkqubo yokuvula nokuvala, ukungqubana phakathi kweflephu ebanzi kunye nomphezulu wokutywina obanzi kuncinci kunokwevalvu yesango, ngoko ke ayigugi. Ukuphakama kokuvula ngokubanzi yi-1/4 kuphela yobubanzi bendlela yesihlalo sevalvu, ngoko ke incinci kakhulu kunevalvu yesango.
Ngokwesiqhelo kukho umphezulu omnye kuphela wokutywina emzimbeni wevalvu kunye nediski yevalvu yevalvu yokumisa, ngoko ke inkqubo yokuvelisa ivalvu yokumisa ilungile, kwaye ivalvu yokumisa kulula ukuyigcina. Uxinzelelo oluqhelekileyo okanye inqanaba loxinzelelo lwevalvu yehlabathi: PN1.0-16.0MPa, ANSI CLASS150-900, JIS
10-20K, ububanzi okanye i-caliber eqhelekileyo: DN10~500, NPS1/2-36, indlela yokudibanisa ivalvu yokumisa: i-flange, i-butt welding, i-thread, njl.njl., ubushushu obufanelekileyo: -1969℃-700℃,
Imo yokuqhuba: ngesandla, i-bevel gear drive, i-pneumatic, i-electric, i-hydraulic, i-gas-liquid linkage, i-electro-hydraulic linkage,
Izixhobo zomzimba ezibanzi: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mо2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti,
Izixhobo ezahlukeneyo zisetyenziselwa ukulungiswa kokunqunyulwa, ezinokusetyenziswa kwiindawo ezahlukeneyo ezifana namanzi, umphunga, ioyile, i-nitric acid, i-acetic acid, i-oxidizing medium, i-urea, njl.njl.
