M'dziko la valve kupanga, kuwongolera ndi mtundu wa zigawo ndizofunikira. Sansheng fluorine pulasitiki imayamba kuwonetsa kuti ili ndi boma lake - la - kujambula luso la epdm + ptfe - ma valve a DNN500. Izi sizimangoganizira za kapangidwe kake komanso chifukwa chosinthasintha mafakitale osiyanasiyana, kuphatikizapo mankhwala ochiritsira, mafuta, ndi magawo a gasi.



Wopangidwa ndi kuphatikiza kwa PTF ndi Fkm, mphete yathu yopirira imatsimikizira kulimba mtima komanso kukana kwa mankhwala osiyanasiyana, kuphatikizapo zodetsa, mafuta, ndi ma acids. Pagawo lapadera limapereka kusinthasintha kwa epdm ndi kukana kwa mankhwala kwa PTF, kupanga chidindo chomwe sichimangokhala ndi PN16, kalasi 150. Kukhazikika kotereku kumapangitsa kuti chisankho chabwino kuyambira PN6 mpaka PN16 (kalasi 150), kuonetsetsa kudalirika komanso kukhala ndi moyo wabwino kwambiri. Amagwiritsa ntchito epdm yathu Mphete ya gulugufe yophika yophika imapitilira kupitirira muizolowerere zofananira ndi matchulidwe monga madzi, mafuta, mafuta, ndi mafuta apansi. Kusintha kumeneku kumaphatikizidwa ndi kuthekera kokwanira mu madoko kukula kuchokera kwa DN50 - DN600, ndikupangitsa kuti ikhale yankho la Valve, mpweya, ndi zofunikira zina za malonda. Zopangidwa ndi kasitomala m'malingaliro, chinthucho chimapezeka mu mawonekedwe a mitundu yomwe amafunsira, kuonetsetsa kuti siongogwira ntchito moyenera komanso zokongoletsa zomwe zimapangitsa kuti pakhale dongosolo lililonse. Ndi zosankha zolumikizana kuphatikizapo mathanthwe komanso miyeso, ndi miyezo yogwirizana ndi ANSI, BS, ND, ndi Jis, mphete yathu yolimba imayimira kuphatikiza kwapadziko lonse lapansi komanso kusinthasintha.
