klase na wafer
+Mas anlemew
+Mas mura
+Mainomay ya pangipuesto
-Kaukolan iray flange na tubo
-Mas mairap ya isentro
-Aliwan matukoy bilang end valve
Diad kaso na Wafer-style butterfly valve, say laman to et annular ya walaan na pigaran ag-ontapew ya abut ed sentro. Arum a klase na Wafer et walaan na duara bangta say arum et walaan na apatiran klase.
Saray flange bolts et isuksok ed saray bolt hole na duaran flange na tubo tan saray center hole na butterfly valve. Diad pangipit ed saray flange bolts, saray flange na tubo et naguyor ed balang sakey tan say butterfly valve et na-clamp ed baetan na saray flange tan mansiansia ed pasen da.
klase na lug
+Matukoy bilang end valve*
+Mas mainomay ya isentro
+Agtanton sensitibo no baleg so pandumaan na temperatura
-Mas ambelat no angkakabaleg so sukat
-Mas mabli
Diad kaso na Lug-style butterfly valve et wala ray tatawagen ya “layag” ed interon kaliberliber na laman ya ditan et intapakan iray sinulid. Diad onian paraan, say butterfly valve et nayarin ipeketan ed kada sakey ed duaran flange na tubo panamegley na 2 nanduruman bolt (sakey ed kada diking).
Lapud say butterfly valve et akapeket ed kada flange ed duaran dapag ya walaan na nanduruman tan mas antikey iran bolts, say tsansan narelaks panamegley na thermal expansion et mas melag nen say Wafer-style valve. Lapud saya, say Lug version et mas matukoy parad saray aplikasyon ya baleg so pandumaan na temperatura.
*Balet, no say Lug-style vavle so usaren bilang sampot a balbula, nepeg ya imanoen so sakey lapud maslak a Lug-style butterfly valves et walaan na abeban sankatageyan a pressure bilang sampot a balbula nen say ipapanengneng na “normal” a klase na presyon da.
