Vharuvhu yeshavishavi yeED Series Wafer ine jira rakapfava uye inogona kupatsanura muviri nepakati pemvura zvakanaka.
Zvinhu zveZvikamu Zvikuru:
| Zvikamu | Zvinhu |
| Muviri | CI,DI,WCB,ALB,CF8,CF8M |
| Dhisiki | DI,WCB,ALB,CF8,CF8M,Rabha Yakanamirwa Disc,Duplex stainless steel,Monel |
| Hunde | SS416,SS420,SS431,17-4PH |
| Chigaro | NBR, EPDM, Viton, PTFE |
| Pin yeTaper | SS416,SS420,SS431,17-4PH |
Tsanangudzo yeChigaro:
| Zvinhu | Tembiricha | Tsananguro Yekushandisa |
| NBR | -23℃ ~ 82℃ | Buna-NBR: (Nitrile Butadiene Rubber) ine simba rakanaka rekukwesha uye inodzivirira kukwesha. Inodzivirirawo zvigadzirwa zvehydrocarbon. Inoshandiswa zvakanaka mumvura, vacuum, acid, salts, alkalines, mafuta, mafuta, hydraulic oils uye ethylene glycol. Buna-N haigone kushandiswa pa acetone, ketones uye nitrate kana chlorinated hydrocarbons. |
| Nguva yekupfura -23℃ ~120℃ | ||
| EPDM | -20 ℃ ~ 130℃ | Rabha reEPDM: irabha rekugadzira rabha rakanaka rinoshandiswa mumvura inopisa, zvinwiwa, masisitimu ezvigadzirwa zvemukaka uye ane ma ketone, doro, nitric ether esters uye glycerol. Asi EPDM haigone kushandiswa mumafuta ane hydrocarbon, zvicherwa kana zvinonyungudutsa. |
| Nguva yekupfura -30℃ ~ 150℃ | ||
| Viton | -10 ℃ ~ 180℃ | Viton i fluorinated hydrocarbon elastomer ine simba rekudzivirira mafuta akawanda emahydrocarbon nemagasi nezvimwe zvigadzirwa zvepetroleum. Viton haigone kushandiswa pabasa remhepo, mvura inopisa inodarika 82℃ kana kuti ine alkaline yakawanda. |
| PTFE | -5℃ ~ 110℃ | PTFE ine kugadzikana kwakanaka kwemakemikari uye pamusoro payo hapazonamati. Panguva imwe chete, ine hunhu hwakanaka hwekunyorovesa uye inodzivirira kukwegura. Chinhu chakanaka chekushandisa mumaacid, alkalis, oxidant nedzimwe ngura. |
| (Muringa wemukati EDPM) | ||
| PTFE | -5℃~90℃ | |
| (NBR yemukati memupendero wemukati) |
Mashandiro:chibatiso, giya, actuator yemagetsi, actuator yepneumatic.
Hunhu:
1. Dhizaini yemusoro we stem ye Double “D” kana Square cross: Yakanakira kubatana nema actuators akasiyana-siyana, inopa torque yakawanda;
2. Chinofambisa simbi yesimbi ine zvikamu zviviri: Hapana nzvimbo yekubatanidza inoshanda kune chero mamiriro asina kunaka;
3. Muviri usina chimiro cheFuremu: Chigaro chinogona kupatsanura muviri nepakati pemvura zvakanyatsonaka, uye zviri nyore kushandisa flange yepombi.
