Switirhisiwa Swa Swiphemu Leswikulu:
| Swiphemu | Swilo |
| Miri | CI,DI,WCB,ALB,CF8,CF8M |
| Disc | DI,WCB,ALB,CF8,CF8M,Rubber Lined Disc,Nsimbi leyi nga riki na swilo swimbirhi,Monel |
| Nsinya | SS416,SS420,SS431,17-4PH |
| Xitulu | NBR,EPDM,Viton,PTFE |
| Taper Pin ya xirhendzevutani | SS416,SS420,SS431,17-4PH |
Xihlawulekisi xa Xitulu:
| Swilo | Mahiselo | Tirhisa Nhlamuselo |
| NBR | -23°C ~ 82°C | Buna-NBR:(Nitrile Butadiene Rubber ) yina matimba ya kahle ya tensile xikan’we naku lwisana na abrasion.Yitlhela yikota ku lwisana na switirhisiwa swa hydrocarbon.I xitirhisiwa xa kahle xa vukorhokeri byo angarhela xo tirhisiwa eka mati,vacuum,acid,salts,alkalines,mafurha,mafurha,greases,hydraulic oils na ethylene glycol. Buna-N ayi tirhisiwi eka acetone,ketones na ti hydrocarbons letinga nitrated kumbe chlorinated. |
| Nkarhi wo duvula-23°C ~120°C | ||
| EPDM | -20 °C ~ 130 °C | General EPDM rubber: i rhaba ya kahle ya general-service synthetic leyi tirhisiwaka eka mati yo hisa, swakunwa, tisisiteme ta switirhisiwa swa masi na letingana ti ketones, byala, nitric ether esters na glycerol. Kambe EPDM ayi nge tirhisi eka mafurha lawa ya sekeriweke eka hydrocarbon, timinerali kumbe swintshuxekisi. |
| Nkarhi wo duvula-30°C ~ 150°C | ||
| Viton | -10 °C~ 180°C | Viton i fluorinated hydrocarbon elastomer leyi nga na ku tiya swinene na mafurha yo tala ya hydrocarbon na tigasi na swin’wana leswi endliweke hi petroliyamu. Viton ayi tirhisiwi eka vukorhokeri bya steam, mati yo hisa kutlula 82°C kumbe ti alkalines leti hlanganisiweke. |
| PTFE | -5°C ~ 110°C | PTFE yina ku tshamiseka ka kahle ka matirhelo ya ti khemikhali naswona vuandlalo a byi nge namarheli.Hi nkarhi lowu fanaka, yina nhundzu ya kahle ya lubricity xikan’we naku lwisana na ku dyuhala. I nchumu wa kahle swinene kuva wutirhisiwa eka ti acids, alkalis, oxidant na swin’wana leswinga corrodents. |
| (Xitirhisiwa xa le ndzeni xa EDPM) | ||
| PTFE | -5°C~90°C | |
| (Xisirhelelo xa le ndzeni NBR) |
Vuhandzuri:lever,gearbox,xitirhisiwa xa gezi,xitirhisiwa xa moya.
Swihlawulekisi:
1.Stem nhloko dizayini ya Double “D” kumbe Square xihambano:Ku olova ku hlanganisa na actuators yo hambana-hambana,ku nyika torque yo tala;
2.Two piece stem square driver:No-space vuhlanganisi byi tirha eka swiyimo swihi na swihi swo biha;
3.Body handle Frame xivumbeko:Xitulu xi nga hambanyisa miri na fluid medium kahle,naswo olova na phayiphi flange.
Xiringaniso: .
Switirhisiwa leswi fambelanaka na swona
