1. Ukusebenza kwamandlaIvalvu yemizi-mveliso :
Ukusebenza kwamandla evalvu kubhekisa kubuchule bevalvu bokumelana noxinzelelo lwesixhobo. Ivalvu yimveliso yoomatshini ethwala uxinzelelo lwangaphakathi, ngoko ke kufuneka ibe namandla aneleyo kunye nokuqina ukuqinisekisa ukusetyenziswa ixesha elide ngaphandle kokuqhekeka okanye ukuguquka.
2. Ukusebenza kokutywina:
Ukusebenza kokuvala kwevalvu kubhekisa kubuchule benxalenye nganye yokuvala yevalvu ukuthintela ukuvuza kwesixhobo. Yeyona ndlela ibalulekileyo yokusebenza kwevalvu. Ivalvu ineendawo ezintathu zokuvala: unxibelelwano phakathi kweendawo zokuvula nezokuvala kunye neendawo ezimbini zokuvala zesihlalo sevalvu; indawo ehambelanayo phakathi kokupakisha kunye nesiqu sevalvu kunye nomzobo wokupakisha; unxibelelwano phakathi komzimba wevalvu kunye nesigqubuthelo sevalvu. Ukuvuza kwangaphambili kubizwa ngokuba kukuvuza kwangaphakathi, okubizwa ngokuba kukuvalwa okuthe tye, okuya kuchaphazela amandla evalvu okusika isixhobo. Kwiivalvu ezivaliweyo, ukuvuza kwangaphakathi akuvumelekanga. Ukuvuza okubini kokugqibela kubizwa ngokuba kukuvuza kwangaphandle, oko kukuthi, ukuvuza okuphakathi ukusuka ngaphakathi kwevalvu ukuya ngaphandle kwevalvu. Ukuvuza kunokubangela ukulahleka kwezinto, kungcolise okusingqongileyo, kwaye kubangele iingozi kwiimeko ezinzima. Kwimidiya evuthayo, eqhumayo, enetyhefu okanye ene-radioactive, ukuvuza akuvumelekanga, ngoko ke ivalvu kufuneka ibe nokusebenza okuthembekileyo kokuvala.
3. Isixa esihambayo:
Emva kokuba i-medium idlule kwi-valve, kuya kubakho ukulahleka koxinzelelo (oko kukuthi, umahluko woxinzelelo ngaphambi nasemva kwe-valve), oko kukuthi, i-valve inokumelana okuthile nokuhamba kwe-medium, kwaye i-medium idla amandla athile ukuze yoyise ukumelana kwe-valve. Ngokwembono yokonga amandla, xa kuyilwa kwaye kusenziwa ii-valve, ukumelana kwe-valve kwi-medium ehambayo kufuneka kuncitshiswe kangangoko kunokwenzeka.

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

Iimveliso eziphambili: iButterfly Valve, iBall Valve, iGate Valve, iCheck Valve, iGlobe Vavve, iiStrainers kunye nee-Electric/Pneumatic Acurators.
