Kutshanje, umzi-mveliso wethu uphumelele umsebenzi wokuvelisa ivalvu yokujonga i-DN300 phantsi kwenkqubo engqongqo yolawulo lomgangatho. Ezi zenziwe ngononophelo kwaye zenziwe ngokuchanekileyo,iivalvu zokujonga amanziAsibonisi nje kuphela ubuchule bethu ekulawuleni ulwelo, kodwa sikwabonisa nokuzinikela kwethu kumgangatho wemveliso. Okwangoku, zonke iivalvu zokujonga zigqibile umsebenzi wokugqibela wokuhlola kwaye zingena kwinqanaba lokupakisha, eliza kuthunyelwa kumthengi.

Njengenxalenye ephambili kwinkqubo yolwelo, umsebenzi ophambili wexabiso levalvu yokujonga kukuthintela ukubuya kombane kunye nokukhusela ukusebenza okukhuselekileyo nokuzinzileyo kwenkqubo yemibhobho. Ivalvu yokujonga ye-DN300 eyenziwe ngumzi-mveliso wethu isebenzisa izixhobo eziphambili kunye netekhnoloji, inokusebenza okuhle kokutywina kunye nokumelana nokugqwala, kwaye ifanelekile kwiimeko ezahlukeneyo zokusebenza ezinzima. Uyilo lwayo olulodwa luqinisekisa ukuba inokuvalwa ngokukhawuleza naphantsi kweemeko zoxinzelelo oluphezulu, iphephe ngempumelelo ukwenzeka kwento yehamile yamanzi, kwaye iqinisekisa ukhuseleko lwenkqubo yonke yemibhobho.

Ivalvu yokujonga ejikelezileyoekusebenziseni amanyathelo okhuseleko:

1. Utolo lubonisa indlela oluhamba ngayo ulwelo, kwaye ukufakelwa kufuneka kuqinisekise ukuba utolo lukhomba kwicala elifanayo nendlela oluhamba ngayo ulwelo, kungenjalo luya kuchaphazela ukusebenza okuqhelekileyo kwevalvu.

2. Ukuze kuqinisekiswe ukusebenza okuzinzileyo kwevalvu yokujonga ixesha elide, kuyacetyiswa ukuba uyijonge kwaye uyigcine rhoqo ngokwemiyalelo yokusebenza, ingakumbi iindawo ezigugileyo ezifana nediski yevalvu kunye nesipringi.

3. Nangona iivalvu zethu zokukhangela ezenziwe ngobuqili zenzelwe ukuba zibe nomthamo wokuthwala uxinzelelo oluphezulu, kusafuneka kuphetshwe ukusetyenziswa koxinzelelo olungaphezulu kolulinganisiweyo ukuze kuthintelwe umonakalo.

Sithembisa ukuba yonke ivalvu yokujonga engabuyiyo ethunyelwayo iya kuthwala ukuzinikela kwethu kumgangatho kunye noxanduva kubathengi bethu. Kwixesha elizayo, umzi-mveliso wethu uya kuqhubeka nokunamathela kwingcamango "yokuvelisa izinto ezintsha, umgangatho, inkonzo", kwaye uphucule rhoqo ukusebenza kwemveliso ukuze kuhlangatyezwane neemfuno ezahlukeneyo zemarike. Kwangaxeshanye, sikwajonge phambili ekusebenzeni namaqabane amaninzi ukukhuthaza kunye uphuhliso kunye nenkqubela phambili yoshishino kunye nokudala ikamva elingcono.
