Nyob rau hauv lub plawv ntawm peb cov khoom yog lub keystone EPDM PTFE npauj npaim valve liner, ib feem tsim rau kev ua tau zoo thiab efficiency. Cov liner no sib xyaw ua ke zoo kawg nkaus resilience ntawm EPDM roj hmab nrog cov tshuaj tsis sib haum xeeb ntawm PTFE, tsim kom muaj lub foob uas tsis tsuas yog ruaj khov tab sis kuj muaj peev xwm ua haujlwm tau zoo thoob plaws qhov kub ntawm - 50 txog 150 degrees Celsius. Qhov kev siv ob npaug no ua kom ntseeg tau tias lub rooj zaum valve tseem ua haujlwm txawm tias nyob rau hauv qhov hnyav tshaj plaws, los ntawm qhov txias txias mus rau qhov kub hnyiab, thiab nyob rau hauv lub ntsej muag ntawm ntau yam tshuaj raug. media xws li dej, dej haus, dej haus, mus rau dej khib nyiab. Qhov kev ua tau zoo no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov chaw kho dej hauv nroog, HVAC systems, thiab cov txheej txheem kev lag luam uas qhov zoo thiab kev ntseeg siab ntawm kev tswj dej yog qhov tseem ceeb. Cov xim dub ntawm lub liner yog ib qho pov thawj rau nws qhov muaj zog, qhia txog lub zog thiab kev ntseeg siab nyob rau hauv nws tsim. Nrog peb cov khoom lag luam, cov neeg ua haujlwm thiab cov kws tsim khoom tuaj yeem ntseeg hauv cov kev daws teeb meem uas ua kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig ntawm kev tswj xyuas dej thiab dej khib nyiab, tswj kev ua haujlwm ruaj khov thiab ua haujlwm txuas ntxiv.
