1. Ngexesha lokufakwa, idiski yevalvu kufuneka imiswe kwindawo evaliweyo.
2. Indawo yokuvula kufuneka imiselwe ngokwe-engile yokujikeleza kwepleyiti yebhabhathane.
3. Kwivalvu yebhabhathane enevalvu ye-bypass, ivalvu ye-bypass kufuneka ivulwe ngaphambi kokuba ivulwe.
4. Ufakelo kufuneka lwenziwe ngokwemiyalelo yofakelo yomenzi, kwaye ivalvu yebhabhathane enzima kufuneka ifakwe ngesiseko esiqinileyo.
5. Ipleyiti yebhabhathane yevalvu yebhabhathane ifakwe kwicala elinobubanzi bombhobho. Kwindlela ye-cylindrical yomzimba wevalvu yebhabhathane, ipleyiti yebhabhathane enemilo yediski ijikeleza i-axis, kwaye i-engile yokujikeleza iphakathi kwe-0° kunye ne-90°. Xa ukujikeleza kufikelela kwi-90°, ivalvu ivuleka ngokupheleleyo.
6. Ukuba kufuneka ivalvu yebhabhathane isetyenziswe njengolawulo lokuhamba kwamanzi, into ephambili kukukhetha ngokuchanekileyo ubungakanani kunye nohlobo lwevalvu. Umgaqo wolwakhiwo lwevalvu yebhabhathane ufanelekile ngokukodwa ekwenzeni iivalvu ezinkulu. Iivalvu zebhabhathane azisetyenziswa kakhulu kuphela kumashishini aqhelekileyo afana nepetroleum, igesi, iikhemikhali kunye nonyango lwamanzi, kodwa zikwasetyenziswa kwiinkqubo zamanzi okupholisa kwizikhululo zamandla obushushu.
7. Iivalvu zebhabhathane ezisetyenziswa rhoqo ziquka iivalvu zebhabhathane ezi-wafer kunye neevalvu zebhabhathane ezi-flange. Ivalvu yebhabhathane yohlobo lwe-wafer isebenzisa ii-bolts ezineentloko ezimbini ukudibanisa ivalvu phakathi kwee-flanges ezimbini zepayipi. Ivalvu yebhabhathane yohlobo lwe-Flange inee-flanges kwivalvu, kwaye ii-bolts zisetyenziselwa ukudibanisa ii-flanges kuzo zombini iziphelo zevalvu kwii-flanges zepayipi.
8. Ipleyiti yebhabhathane yevalvu yebhabhathane ifakwe kwicala elinobubanzi bombhobho. Kwindlela ye-cylindrical yomzimba wevalvu yebhabhathane, ipleyiti yebhabhathane enemilo yediski ijikeleza i-axis, kwaye i-engile yokujikeleza iphakathi kwe-0° kunye ne-90°. Xa ukujikeleza kufikelela kwi-90°, ivalvu ivuleka ngokupheleleyo.
INortech ngomnye wabavelisi beevalvu zoshishino abaphambili eTshayina abanesiqinisekiso somgangatho se-ISO9001.
