| Thupi | CI,DI,WCB,ALB,CF8,CF8M |
| Disiki | DI,WCB,ALB,CF8,CF8M,Rubber Lined Disc,Duplex stainless steel,Monel |
| Tsinde | SS416,SS420,SS431,17-4PH |
| Mpando | NBR, EPDM, Viton, PTFE |
| Pin Yopopera | SS416,SS420,SS431,17-4PH |
Mafotokozedwe a Mpando:
| Zinthu Zofunika | Kutentha | Kufotokozera kwa Ntchito |
| NBR | -23℃ ~ 82℃ | Buna-NBR: (Nitrile Butadiene Rubber) ili ndi mphamvu yokoka komanso yolimba kuti isapse. Imalimbananso ndi zinthu za hydrocarbon. Ndi chinthu chabwino chogwiritsidwa ntchito m'madzi, vacuum, acid, salt, alkalines, mafuta, mafuta, mafuta a hydraulic ndi ethylene glycol. Buna-N singagwiritsidwe ntchito pa acetone, ketones ndi ma hydrocarbons a nitrate kapena chlorinated. |
| Nthawi yowombera - 23℃ ~ 120℃ | ||
| EPDM | -20 ℃ ~ 130℃ | Rabala ya EPDM: ndi rabala yabwino yopangidwa ndi anthu onse yomwe imagwiritsidwa ntchito m'madzi otentha, zakumwa, makina opangira mkaka ndi omwe ali ndi ma ketones, mowa, nitric ether esters ndi glycerol. Koma EPDM singagwiritsidwe ntchito pamafuta okhala ndi hydrocarbon, mchere kapena zosungunulira. |
| Nthawi yowombera - 30℃ ~ 150℃ | ||
| Viton | -10 ℃ ~ 180℃ | Viton ndi fluorinated hydrocarbon elastomer yomwe imalimbana bwino ndi mafuta ambiri a hydrocarbon ndi mpweya ndi zinthu zina zopangidwa ndi mafuta. Viton singagwiritsidwe ntchito popereka nthunzi, madzi otentha opitirira 82℃ kapena ma alkaline ambiri. |
| PTFE | -5℃ ~ 110℃ | PTFE ili ndi mphamvu yabwino yogwira ntchito ndi mankhwala ndipo pamwamba pake sipadzakhala pomata. Nthawi yomweyo, ili ndi mphamvu yabwino yopaka mafuta komanso yolimba. Ndi chinthu chabwino chogwiritsidwa ntchito mu ma acid, alkalis, oxidant ndi zina zowononga. |
| (Cholumikizira chamkati cha EDPM) | ||
| PTFE | -5℃~90℃ | |
| (NBR yamkati) |
Ntchito:lever, gearbox, actuator yamagetsi, actuator ya pneumatic.
Makhalidwe:
1. Kapangidwe ka mutu wa stem wa Double “D” kapena Square cross: Kosavuta kulumikizana ndi ma actuator osiyanasiyana, kumapereka mphamvu yowonjezereka;
2. Choyendetsa cha tsinde cha zidutswa ziwiri: Kulumikizana kopanda malo kumagwira ntchito pazovuta zilizonse;
3. Thupi lopanda chimango: Mpando ukhoza kulekanitsa thupi ndi madzimadzi bwino, komanso mosavuta ndi chitoliro cha chitoliro.
