Mubice bigenzura inganda, guhuza ibikoresho byiza hamwe nigishushanyo nyaburanga ni icyambere. Ikinyugunyugu cyurufunguzo rwa Valve 990 ugaragaza iri hame, ritanga igisubizo cyisumbuye cyo gucunga neza kandi byizewe. Imyenda ya Shoorine ya Sansheng, iyi valve igabanya ubukana bwa EPDM na PTFE, ishyiraho urwego rusanzwe rwimikorere Ikigo cya PTFE (PolytetrafLoroioRylene) na EPDM (Esylene Propaylene Diene Monomer). Uku guhuza ntabwo ari ugukemura gusa imiti itemewe ariko itanga kandi ubushyuhe bunini bwa - 40 ° C kugeza 135 ° C, bigatuma bikwiranye nibitangazamakuru bitandukanye, mumazi kugeza ibintu byinshi bikaze. Fusion ya PTFE na EPDM itezimbere kuramba, bituma bituma bahanganye nibihe bitabangamiye utabangamiye imikorere cyangwa ubunyangamugayo.



Yagenewe gusobanuka, valve yakira igice kinini cyinshi muri DN50 kuri DN600, iremeza ko bikwiye kuri sisitemu iyo ari yo yose. Gushyira mu bikorwa ikinyugunyugu, cyane cyane ubwoko bwa Wafer Cerecalline yoroshye ya salle yoroshye ya kato na pneumatike wafer, byerekana guhuza n'imihindagurikire y'ibinyugunyuza no gukora neza mu kugenzura. Valve yirata ibara ryirabura, hamwe nuburyo bwo guhuza harimo byombi wafer kandi birangira neza, bitanga guhinduka mugushiraho no kubungabunga. Hamwe nicyicaro cyicaro nka EPDM, NBR, EPR, PTFE, nibindi byinshi bya Valve 990 Plastike yishyize mu bikorwa urufunguzo rw'ikinyukingo cya valeve 990 kugirango abone ibisabwa n'inganda zigezweho. Muguhuza gukomera kwa EPRODM hamwe no kwihangana kwa PTFE, iyi valve itanga imikorere itagereranywa, iba ikorwa neza no kugenzura muri sisitemu aho kwizerwa. Yaba ari ibihingwa byo gutunganya amazi, ibikoresho byo gutunganya imiti, cyangwa sisitemu ya HVAC, ikinyugunyugu chantston valve 990 ihagaze mu Isezerano ryiza no guhanga udushya mubisubizo byubuyobozi.
