- I-eccentricity yesithathu: Uyilo lwe-engile ye-cone yokutywina ifezekisa ukutywinwa okuqinileyo kwesinyithi.

- Iingenelo:

- Zero friction ukuvula nokuvalwa: Ipleyiti ye-valve kunye nesihlalo se-valve sidibanisa kuphela xa ivaliwe, eyandisa ubomi benkonzo.

- Ubushushu obuphezulu kunye nokumelana noxinzelelo oluphezulu: Izitywina zentsimbi ziyakwazi ukumelana nokushisa okuphezulu ngaphezu kwe-400 ℃ kunye namanqanaba oxinzelelo lwe-Class 600.

- Ukutywinwa kabini: Ifanelekile kwiimeko zokusebenza ezinzima apho i-medium ihamba kumacala omabini.

- Iimeko zesicelo: Iinkqubo eziphambili ezinobushushu obuphezulu kunye noxinzelelo oluphezulu njengamandla, i-petrochemical, kunye ne-LNG.

4. Ukusebenza okuphezulu kweValve yebhabhathane

- Ingcaciso: Ngokuqhelekileyo ibhekisela kwi-valve ye-butterfly ene-double eccentric okanye i-triple eccentric structure, eneempawu ze-torque ephantsi, ukutywinwa okuphezulu kunye nobomi obude.

- Iinzuzo eziphambili: Inokutshintsha ezinye iivalvu zesango kunye neevalvu zebhola kunye nokunciphisa iindleko zeenkqubo zemibhobho.

Kutheni ivalve yebhabhathane ye-eccentric ilukhetho lokuqala kushishino

 1. Uhlalutyo lweenzuzo zesakhiwo

- Uyilo oluqinileyo lwentsimbi: Yenziwe ngensimbi engenasici, intsimbi ye-alloy kunye nezinye izinto, ayinakugqwala kwaye ayigugi.

- Umphezulu wokutywina weConical: Uqhagamshelwano oluqhubekayo lwenziwa xa kuvalwa, kwaye itywina liqina.

- Uyilo lokhuseleko lomlilo: ezinye iimodeli zidibana ne-API 607 ​​​​yesatifikethi somlilo kwaye zifanelekile kwindawo ezinobungozi.

2. Uthelekiso kunye nevalve yebhabhathane ene-eccentric ephindwe kabini

3. Amatyala ezicelo zeshishini
