Txheem AISI304 lossis 316 stainless hlau rooj vag yog grinded thiab polished smoothly raws li daim iav, uas tuaj yeem zam kev puas tsuaj ntawm cov ntim thiab lub rooj los ntawm kev qhib lossis kaw thiab ua kom muaj kev sib khi ntau dua. Hauv qab ntawm lub rooj vag ntug yog machined rau ib tug bevel, thiaj li hais tias nws txiav los ntawm cov khib nyiab rau ib tug tighter foob nyob rau hauv kaw txoj hauj lwm. Ib rab riam tiv thaiv tuaj yeem muab kev tiv thaiv ntxiv rau cov plua plav.
Nws muaj 3 yam zoo li hauv qab no:
1. Standard lub rooj zaum NBR, EPDM, kuj muaj nyob rau hauv PTFE, Viton, Silicone thiab lwm yam. Cim tsim uas mechanically locks lub foob nyob rau hauv lub sab hauv ntawm lub valve lub cev nrog ib tug stainless hlau retainer nplhaib. Feem ntau nws yog unidirectional foob tsim, thiab bidirectional foob raws li thov.
2. Ob peb txheej ntawm braided packing nrog ib qho yooj yim nkag mus packing caj pas kom ntseeg tau ib tug nruj seal. Muaj nyob rau hauv ntau yam ntaub ntawv: Graphite, PTFE, PTFE + KEVLAR thiab lwm yam.
3. Cov lus qhia thaiv ntawm lub valve lub cev ua rau lub rooj vag txav mus kom raug, thiab cov khoom thaiv extrusion ua kom muaj kev sib khi zoo ntawm lub rooj vag.
ZFA Valve nruj me ntsis ua raws li tus qauv API598, peb ua ob sab kev ntsuas siab rau tag nrho cov valve 100%, lav xa 100% zoo li qub rau peb cov neeg siv khoom.
Lub cev lub cev txais GB cov khoom siv, muaj tag nrho 15 txheej txheem los ntawm hlau mus rau lub cev valve.
Kev tshuaj xyuas zoo los ntawm qhov khoob mus rau cov khoom tiav yog 100% lav.
