uri ning wafer
+Mas magaan
+Mas mura
+Madali yang i-install
-kailangan la reng flanges ning pipa
-Mas masakit ing isentru
-E ya masanting bilang end valve
keng kasu ning Wafer-style butterfly valve, ing katawan na annular ya ampo atin yang mapilan a non-tapped centering holes. Deng mapilan a uri ning Wafer atin lang adwa kabang deng aliwa atin lang apat.
Deng flange bolts mipasulud la kareng bolt holes da reng adwang pipe flanges ampo reng centering holes ning butterfly valve. kapamilatan ning pamaghigpit kareng flange bolts, ding flange ning pipa miguguyud la papunta king metung at metung at ing butterfly valve maka-clamp ya pilatan da reng flange at maka-hold ya king lugal na.
Uri ning lug
+angay ya bilang end valve*
+Mas mayan isentru
+Mas ditak ing sensitibo nung maragul ing pamiyaliwa ning temperatura
-Mas mabayat kareng mas maragul a sukad
-Mas mahal
keng kasu ning Lug-style butterfly valve atin yang awsan dang "balugbug" keng mabilug a paligid ning katawan nung nukarin la mitapik deng sinulad. king makanyan a paralan, ing butterfly valve malyari yang masipit keng balang metung kareng adwang pipe flanges kapamilatan da reng adwang miyayaliwang bolts (metung keng balang gilid).
Uling ing butterfly valve makadikit ya keng balang flange keng adwa nang gilid kareng miyayaliwang, mas makuyad a bolts, ing chance ning pamagrelaks kapamilatan ning thermal expansion mas malati ya kesa keng Wafer-style valve. Uli na niti, ing Lug version mas masanting ya para kareng aplikasyun a ating maragul a pamiyaliwa keng temperatura.
*Dapot, nung ing Lug-style vavle ing gamitan bilang end valve, dapat yang pansinan uling keraklan kareng Lug-style butterfly valves atin lang mas mababa a maximum a pressure bilang end valve kesa keng karelang “normal” a pressure class.
