Umvelisi weValve ye-NSWIbonelela ngemizimba yeevalvu ezenziwe ngokwezifiso ezenzelwe iimeko zobushushu obuphezulu, ezirhabaxa, okanye ezirhabaxa, ukuqinisekisa ukuthotyelwa kwemigangatho ye-API, i-ANSI, kunye ne-ASME.

Ibhola: I-Core Flow Control Element

Iibholasisiqwenga esiphambili sevalvu, sijikeleza ngama-90° ukulawula ukuhamba kolwelo.Umvelisi weValve ye-NSWivelisa iintlobo ezimbini:

- Iibhola Ezidadayo: Ilungele uxinzelelo oluphantsi ukuya koluphakathi.

- Iibhola zeTrunnion: Kwiinkqubo ezinoxinzelelo oluphezulu (umz., ioyile negesi).

Iimpawu zoYilo:

- Izixhobo: Intsimbi engatyiwayo, iiseramikhi, okanye i-PTFE-coated ukuze ikwazi ukumelana neekhemikhali.

- Iintlobo zeBore: Izibuko elipheleleyo (ukuhamba kwe-100%) xa kuthelekiswa nezibuko elincitshisiweyo (ukuhamba kwe-80%).

- Iindlela zokutywina:

–Izitywino ezithambileyo: I-PTFE okanye ii-elastomers zokuthintela ukuvuza okungavuziyo.

–Izitywina Eziqinileyo: Isinyithi-kwisinyithi xa kushushu kakhulu.

In Iivalvu zebhola ezineendlela ezintathuukusukaUmvelisi weValve ye-NSW, iibhola ezinamachweba amaninzi zivumela ukuphambuka, ukuxuba, okanye ukuvala ukuhamba kwamanzi kwiinkqubo ezintsonkothileyo.

Isihlalo seValve yeBhola: Ukuqinisekisa Ukusebenza Okungenamanzi

Iisihlalo sevalvuyenza uphawu oluqinileyo phakathi kwebhola nomzimba.Umvelisi weValve ye-NSWkusetyenziswa:

- Izihlalo ezithambileyo: I-PTFE, i-NBR, okanye i-EPDM kwizicelo ezisebenzisa ubushushu obuphantsi.
- Izihlalo Eziqinileyo: Intsimbi engatyiwayo, iStellite, okanye i-tungsten carbide yezixhobo zokurhawuzelela.

Uyilo lweZitulo ezintsha:

- Ukuvimba kabini kunye nokopha (DBB): Yahlula ukuhamba kwamanzi angasentla/asezantsi ukuze kugcinwe ukhuseleko.

- Ukuzicoca: Izikrweqe zisusa inkunkuma, zandisa ubomi besihlalo xa kusetyenzwa udaka.

- Ivalvu Yokwahlulwa Kabini kunye neValve Yokopha (DIB): Yivalvu yebhola enezibini ezimbini zokutywina izihlalo zeevalvu. Isibini ngasinye sokutywina isihlalo sevalvu sinika kuphela ukutywina komthombo omnye woxinzelelo xa sikwindawo evaliweyo, kwaye sikhupha/sikhuphe umgodi womzimba wevalvu phakathi kweendawo ezimbini zezihlalo zeevalvu ukuze kuqinisekiswe ukutywina koxinzelelo kuzo zombini iziphelo.
