AWWA C504 butterfly valve ine mafomu maviri, midline line soft seal uye double eccentric soft seal, kazhinji, mutengo we midline soft seal uchave wakachipa kupfuura eccentric mbiri, hongu, izvi zvinowanzoitwa maererano nezvinodiwa nevatengi.Kazhinji kushanda nesimba kweAWWA C504 ndeye 125psi, 150psi, 250psi, flange yekubatanidza pressure rate ndeye CL125, CL150, CL250.
AWWA C504 butterfly valve inonyanya kushandiswa mumapurojekiti ekurapa mvura, iyo inodiwa yepakati imvura isina tsvina, maitiro echisimbiso cherubha anosimbisa kushanda kwekuvhara kwevhavha, kuitira kuti valve iwane 0 leakage.Mukusarudzwa kwevhavha yemuviri zvinhu, kazhinji ductile iron ndiyo huru, inoteverwa nekabhoni simbi inogoneka zvakare.Sarudzo yevhavha disc sealing ring, EPDM, NBR, NR iripo, zvinoenderana nezvinodiwa nemutengi kuita sarudzo.
Kuenzaniswa ne EN558-13,14 yakatevedzana butterfly mavharuvhu, AWWA C504 butterfly valve ine muviri wakakora uye dhayamita dhayamita yakakora, uye kunewo misiyano mishoma mune mamwe madhiyamu, ayo anogona kuonekwa mune inotevera dimension table.Zvechokwadi, nokuda kwebasa racho, hapana mutsauko mukuru nemamwe mavharuvhu erubha-akavharwa.
Ndevapi vagadziri vanogona kugadzira AWWA C504 butterfly valve muChina?Sekuziva kwangu, hapana vagadziri vakawanda vanogona kugadzira AWWA C504 butterfly valve, mafekitari mazhinji ane ruzivo rwakawanda mukugadzira EN558-13/14 yakatevedzana butterfly valve, uye havana ruzivo rwakawanda mukugadzira AWWA C504 butterfly valve, Tianjin Zhongfa. Valve ndeimwe yevagadziri vanogona kugadzira AWWA C504 butterfly valve, Zhongfa Valve ine mold yayo uye yayo pachayo yekugadzirisa workshop, iyo inogona kupedzisa kugadzirwa kwevhavhavhavha ine mhando uye huwandu.
Inotevera ivhavhavhavhavhavha yeAWWA C504 inogadzirwa naTianjin Zhongfa Valve, Kana iwe uchida kuziva zvakawanda nezve AWWA C504 zvigadzirwa, unogona zvakare kutibata.
