Madow/Cagaar PTFE/FPM + EPDM Rubber Valve Kursiga Kursiga Valve Balanbaalista
PTFE + EPDM Kuraasta caagga ah ee isku dhafan ee ay soo saarto SML ayaa si weyn loogu isticmaalaa dharka, xarunta korontada, petrochemical, kululaynta iyo qaboojiyaha, dawooyinka, dhismaha maraakiibta, birta, warshadaha iftiinka, ilaalinta deegaanka iyo meelo kale.
Waxqabadka badeecada: caabbinta heerkulka sare, caabbinta acid wanaagsan iyo alkali iyo caabbinta saliidda; leh adkeysi soo kabasho wanaagsan leh, adag oo waara iyada oo aan dareerin.
PTFE+EPDM
Xadhkaha Teflon (PTFE) waxa uu dulsaaraa EPDM kaas oo ku xidhan giraan adag oo phenolic ah oo ku yaala wareegga kursiga ee dibadda. PTFE waxay ku fidsan tahay wejiyada kursiga iyo bannaankaba dhexroorka shaabadda flange, oo si buuxda u daboolaya lakabka elastomer-ka ee EPDM ee kursiga, kaas oo siiya adkeysi loogu talagalay xiridda afkoda waalka iyo saxanka xiran.
Heerkulka: -10°C ilaa 150°C.
Budada PTFE (Polytetrafluoroethylene)
PTFE (Teflon) waa polymer-ka ku salaysan fluorocarbon oo caadiyan ah kan ugu adkaysiga badan kiimikaad ee balaastikada oo dhan, iyadoo ilaalinaysa sifooyin heer sare ah oo kuleyl iyo koronto ah. PTFE sidoo kale waxay leedahay iskudhaf hoose oo is jiid jiid ah sidaa darteed waxay ku habboon tahay codsiyo badan oo qulqulka hooseeya.
Walaxdani maaha -wax wasakhaysan oo ay aqbasho FDA ee codsiyada cuntada. Inkasta oo sifooyinka farsamada ee PTFE ay hooseeyaan, marka la barbardhigo balaastikada kale ee la farsameeyey, hantidoodu waxay ahaanayaan kuwo faa'iido leh oo ka badan heerkul ballaaran.
Heerkulka: -38°C ilaa +230°C.
Midabka: cad
Xadhkaha garaaca: 0%

Keystone Balanbaalis Valve Seling Rings waxaa si heersare ah looga farsameeyay isku darka adag ee PTFE iyo EPDM. Isku dhafkan kaliya ma xaqiijinayo adkeysi aan la qiyaasi karin oo ka soo horjeeda heerkulka sare laakiin sidoo kale wuxuu bixiyaa iswaafajin gaar ah oo leh noocyo kala duwan oo warbaahin ah. Haddi ay tahay baahida adag ee warshada batroolka, saxnaanta looga baahan yahay wax soo saarka dawooyinka, ama adkaynta looga baahan yahay warshadaha birta, siddooyinkan xidhidhisku waxay u taagan yihiin dhagaxa u dhigma xakamaynta dareeraha giraangiraha waxay u adeegaan tiro balaadhan oo ah cabbirka dekeda laga bilaabo DN50 ilaa DN600, hubinta ku haboon Habaynyo kala duwan oo balabalisooyin ah oo ay ku jiraan Wafer Type Centerline Soft Seling Butterfly Valve iyo pneumatic Wafer Butterfly Valve. Naqshaddooda sare waxaa kaabaya fududaynta is dhexgalka ee Nooca Lug-ga ee Laba-jibbaaran ee Shaft Butterfly Valves oo aan lahayn biin, taasoo ka dhigaysa inay xal u helaan injineerada iyo xirfadlayaasha raadinaya isku hallayn la'aan adag. Marka laga soo tago mudnaantooda farsamo, kursiga madow/cagaaran ee PTFE/FPM + EPDM Rubber Valve Kursiga waxa uu soo kordhiyaa adkeysiga iyo isku halaynta xaaladaha walaaca sare, iyada oo hubinaysa in hawlahaagu ay si habsami leh ugu socdaan xaaladaha heerkulka sare.
