Ukukhetha umthengisi weevalvu zePVC sisigqibo esibalulekileyo. Khetha ongafanelekanga, kwaye ubambeke kwiimveliso ezivuzayo, abathengi abanomsindo, kunye nodumo olonakeleyo. Yingozi ongenakukwazi ukuyihlawula.

Ivalvu yebhola yePVC "eyona ilungileyo" ivela kumvelisi onikezela ngomgangatho ohambelanayo, iziqinisekiso eziqinisekisiweyo, kunye nothungelwano lokubonelela oluthembekileyo. Igama lophawu alibalulekanga kangako kunokuzinikela kwabo ekusebenziseni i-100% virgin PVC, izitywina ze-EPDM ezihlala ixesha elide, kunyeuvavanyo loxinzeleloivalvu nganye.

Lo mbuzo wokuba “ngubani ongcono” awungowokufumana uphawu oludumileyo. Ungowokufumana iqabane elithembekileyo. Ngumxholo wencoko yam nabaphathi bokuthenga abanjengoBudi eIndonesia. Akathengi nje kuphela into ethile; uthenga isithembiso somgangatho aze asidlulisele kubathengi bakhe. Ivalvu “engcono” yileyo ifika ngexesha, isebenza ngokugqibeleleyo ngalo lonke ixesha, kwaye ixhaswa ngumvelisi oxhasa imveliso yakhe. Olu themba lwakhiwe kwisiseko somgangatho wezinto eziphathekayo, ulawulo lwemveliso, kunye nokuqonda okunzulu oko kufunekayo ukuze uphumelele.

Yeyiphi ivalvu yebhola yenkampani engcono?

Uthelekisa iikowuteshini ezivela kwiinkampani ezininzi. Uxhalabile kukuba ukukhetha nje eyona ingabizi kakhulu kuya kukhokelela ekuweni kwemveliso okuya konakalisa udumo lweshishini lakho ekuhambeni kwexesha.

Eyona nkampani ibalaseleyo yileyo ibonisa umgangatho ohambelanayo ngokukhetha izinto (i-PVC eyi-100% engabonakaliyo), uvavanyo oluqatha (ivalvu nganye ivavanyiwe), kunye nobonelelo oluthembekileyo. Khangela abavelisi abanemisebenzi yabo yonke, njengathi ePntek.

Eyona nkampani ibalaseleyo yileyo ikumgangatho wayo owakhelwe kuyo yonke inyathelo lenkqubo. Xa uBudi efumana iivalvu, akathengi nje iplastiki; uthenga ukuthembeka kwayo yonke inethiwekhi yakhe yokusasaza. Abavelisi ababalaseleyo abakuthengiseli nje imveliso; baxhasa ishishini lakho. Oku sikufezekisa ngokugxila kwiintsika ezintathu:Ubumsulwa bezinto ezibonakalayo, Ulawulo lweMvelisokunyeUkuthembeka kweTyathanga loNikezeloUmzekelo, sisebenzisa kuphela i-PVC eyi-100% emsulwa, izinto zokuzalisa ezingaphinda zisetyenziswe, ezithintela ukuqhekeka kwaye ziqinisekisa amandla. Ukuveliswa kwethu ngokuzenzekelayo kunye novavanyo loxinzelelo lomntu ngamnye kwivalvu nganye kuqinisekisa ukuba oko uBudi akufumanayo kwisikhongozeli sakhe se-100 kufana ngomgangatho nowokuqala. Eli nqanaba lolawulo yilo lichaza inkampani "engcono" - leyo ungayithemba ngaphandle kokubhukisha.

Yintoni Echaza Inkampani "Eyona Ibalaseleyo"

Ngubani owenza izixhobo zePVC ezilungileyo?

Ufumene umthengisi weevalvu olungileyo, kodwa ngoku udinga izixhobo zokufakelwa. Ukuthenga kwinkampani eyahlukileyo kongeza ubunzima kunye nemingcipheko yokungalingani kweendawo, nto leyo ebangela iintloko zokufakelwa kubathengi bakho.

Ii-PVC fittings ezilungileyo zihlala zivela kumvelisi ofanayo owenza iivalvu zakho. Umthengisi we-Pntek osebenzisa umthombo omnye uqinisekisa ukuhambelana okugqibeleleyo ngobukhulu, umbala, kunye nemigangatho yezinto eziphathekayo, okwenza kube lula ukuthenga kwakho kwaye kuqinisekisa ukulingana okungenamthungo.

Ingqiqo apha imalunga nokudala inkqubo egqibeleleyo. Umgca wombhobho unamandla kuphela xa uqhagamshelo lwawo lubuthathaka. Xa amaqabane am efumana iivalvu kuthi, ndisoloko ndicebisa ukuba nabo bafumane izixhobo zethu. Kutheni? Kuba silawula yonke inkqubo yendalo. Iivalvu zethu zeShedyuli 80 zenzelwe ukuba zihambelane ngokugqibeleleyo nobunzulu besokethi kunye nokunyamezela kwezixhobo zethu zeShedyuli 80. Oku akusoloko kunjalo xa uxuba kwaye udibanisa iimpawu ezivela kwiifektri ezahlukeneyo. Umahluko omncinci ekunyamezeleni unokukhokelela kwijoyinti ekhululekileyo kakhulu—umngcipheko omkhulu wokuvuza. Ngokufumana yonke inkqubo kumvelisi omnye othembekileyo, umthengi onjengoBudi wenza lula izinto zakhe kwaye anike abathengi bakhe isisombululo esipheleleyo nesiqinisekisiweyo. Oku kuba yindawo yokuthengisa enamandla kubakhi bakhe; bayazi ukuba yonke into iya kusebenza kunye ngokugqibeleleyo.

Ingakanani ixesha lokuphila kwevalvu yebhola yePVC?

Ufaka ivalvu yePVC kwaye unethemba lokuba iza kuhlala ixesha elide. Kodwa ngaphandle kokwazi ukuba iza kuhlala ixesha elide, awunakuceba ukugcinwa okanye uqinisekise ukuthembeka kwabathengi bakho.

Ivalvu yebhola yePVC esemgangathweni ophezulu nefakelwe ngokufanelekileyo inokuhlala iminyaka engama-20 nangaphezulu kwinkqubo yamanzi abandayo. Izinto eziphambili ezichaphazela ubomi bayo kukuvezwa yi-UV, uxinzelelo lokusebenza, ubushushu, kunye nomgangatho wezinto ezisetyenzisiweyo.

Ixesha lokuphila alilonani linye; lisiphumo sokwenziwa komgangatho kunye nokusetyenziswa ngokufanelekileyo. Ivalvu efakwe ngaphakathi, ikhuselwe elangeni, kwinkqubo yoxinzelelo oluphantsi ingasebenza amashumi eminyaka. Ivalvu efanayo efakwe ngaphandle ngaphandle kokhuseleko inokuba buthathaka ngenxa yemitha ye-UV kwiminyaka emi-5-10. Yingakho songezaIzithinteli ze-UVkwifomula yethu yePVC ePntek. Ngokufanayo, ivalvu esebenza ngaphakathi komlinganiselo wayo woxinzelelo iya kuhlala ixesha elide, ngelixa umntu osebenzisa ihamile yamanzi rhoqo enokungaphumeleli kungekudala. Xa ndithetha namaqabane, ndigxininisa ukuba imveliso esemgangathweni inikaamandlaubomi obude. Sakha kuloo mandla ngezitywino ze-EPDM ezikumgangatho ophezulu ezingayi komelela kunye nezihlalo ze-PTFE ezingagugiyo. Ixesha lokugqibela lokuphila limiselwa kukusetyenziswa ngokuchanekileyo. Ukukhetha isixhobo esenziwe kakuhleivalvukuthetha ukuba uqala ngelona thuba liphezulu lokuphila ixesha elide.

Zeziphi iivalvu zebhola ezenziwe eMelika?

Iprojekthi yakho ichaza iimveliso "Ezenziwe eMelika". Ukukhangela ababoneleli ukuze ufumane iimpawu zokwenyani ezenziwe eMelika kunokuthatha ixesha elide kwaye kudide, kubambezele iikowuteshini kunye neeodolo zakho.

Iimpawu ezininzi ezaziwayo ezifana neSpears, Hayward, kunye neNibco zenza iivalvu zebhola zePVC e-USA. Ezi zihlonitshwa ngenxa yomgangatho wazo kodwa zihlala zinexabiso eliphezulu ngenxa yeendleko zasekhaya.

Lo ngumbuzo wokufumana icebo kunye neemfuno zeprojekthi. Kwiiprojekthi ezininzi e-US, ingakumbi iikhontrakthi zikarhulumente okanye ezithile zemizi-mveliso, kukho imfuneko engqongqo yezinto ezifumaneka ngaphakathi. Iimpawu ezifana neSpears Manufacturing kunye neHayward Flow Control zinembali ende yokwenza iivalvu ezikumgangatho ophezulu e-USA. Nangona kunjalo, kumthengi wehlabathi njengoBudi e-Indonesia, le ayisiyonto iphambili ayixhalabileyo. Ingqwalasela yakhe kukufumana ulungelelwaniso olungcono lomgangatho, ukuthembeka, kunye nexabiso kwimarike yakhe. Umenzi wehlabathi ofanaI-Pntek, ngemveliso ezenzekelayo ephucukileyo, inokubonelela ngemveliso ehlangabezana okanye edlula imigangatho yomgangatho wamazwe ngamazwe njenge-ISO 9001 kunye ne-CE ngexabiso elikhuphisanayo ngakumbi. Ukhetho "olungcono" luxhomekeke kwiimfuno ezithile zomthengi wokugqibela: Ngaba ngumthetho ongqongqo othi "Made in USA", okanye ngaba ufumana ukusebenza okuphezulu kotyalo-mali?

Isiphelo

Egqibeleleivalvu yePVCIvela kwiqabane lomenzi eliqinisekisa umgangatho, ukuhambelana, kunye nothungelwano lokubonelela oluthembekileyo, kungakhathaliseki ukuba ligama lophawu okanye ilizwe elivela kulo.
