(1) ulwakhiwo lwevalvu yeglobe lulula kunevalvu yesango, kwaye ukwenziwa nokugcinwa kwayo kulula ngakumbi.
(2) umphezulu wokutywina akulula ukuwunxiba nokukrwela, ukutywina kakuhle, ukuvula nokuvala phakathi kwediski yevalvu kunye nomphezulu wokutywina umzimba wevalvu ngaphandle kokutyibilika, ngoko ke ukukrala nokukrwela akuyonto inzima, ukusebenza kakuhle kokutywina, ubomi benkonzo ende.
(3) xa uvula naxa uvala, i-disc stroke incinci, ngoko ke ukuphakama kwevalvu yeglobe kuncinci kunevalvu yesango, kodwa ubude besakhiwo bude kunevalvu yesango.
(4) i-torque yokuvula nokuvala inkulu, ukuxinana kokuvula nokuvala kunzima, ixesha lokuvula nokuvala libaluleke kakhulu.
(5) ukuxhathisa kolwelo kukhulu, kuba umjelo ophakathi emzimbeni wevalvu uyagungqa, ukuxhathisa kolwelo kukhulu kwaye ukusetyenziswa kwamandla kukhulu.
(6) xa uxinzelelo oluqhelekileyo lwe-Pn kwicala lokuhamba okuphakathi lungaphantsi okanye lulingana ne-16Mpa, luhlala lusezantsi, kwaye oluphakathi luhamba ukusuka kwicala elisezantsi lediski yevalvu; Uxinzelelo oluqhelekileyo lwe-Pn ≥ 20Mpa, ngokubanzi sebenzisa umbane ochaseneyo, ukuhamba okuphakathi ukusuka kwicala lediski. Ukwandisa amandla okutywina. Xa isetyenziswa, ivalvu yokusika inokuthi ihambe kwicala elinye kuphela kwaye ayinakutshintsha icala lokuhamba.
(7) xa ivuliwe ngokupheleleyo, idiski idla ngokubola.
I-axis yesiqu sevalvu yevalvu yeglobe imile nkqo kumphezulu wokutywina wesihlalo sevalvu. I-stem open/close stroke imfutshane kwaye inesenzo sokunqumla esithembekileyo kakhulu, nto leyo eyenza le valve ifaneleke ukusetyenziswa kokunqumla okuphakathi okanye ukulawula kunye nokucinezela.

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

Iimveliso eziphambili:Ivalvu yebhabhathane,Ivalvu yeBhola,Ivalvu yeSango,Jonga iValve,IGlobe Vavlve,Ii-Y-Strainers,Isixhobo sombane,Ii-Acurators ze-Pneumatic.
