ʻO ka "150 butterfly valve" maʻamau e pili ana i ʻelua mau palena maʻamau:
- DN150: Anawaena inoa 150mm (like me 6 ʻīniha ma NPS).
- 150lb / 150 / Papa 150: Ka helu kaomi ANSI/ASME Papa 150 (ma kahi o 150 psi, maʻamau i nā ʻōnaehana maʻamau ʻAmelika, like me PN20 ma Kina/Kelemānia).
1. Nā Ana o ka Pāpale Pepeiao DN150 / 6"
ʻO nā ʻano valve butterfly e komo pū me Wafer, Lug, a me Double Flanged. Hōʻuluʻulu ka ʻikepili ma lalo nei i nā palena koʻikoʻi e pili ana i nā kūlana e like me ASME B16.5.
1.1 ʻAno Wafer/Lug (ʻAno Clip-on/Lug, pilina pōkole maʻamau, kūlike me ISO 5752):
- Ka lōʻihi o ke alo a i ke alo: 55–57 mm
- Ke kiʻekiʻe holoʻokoʻa (ʻau ʻōlohelohe me ka ʻole o ka actuator): 320–400 mm (hana concentric/kiʻekiʻe)
- Ka nui o ke koʻokoʻo:≈14*14mm
1.2 ʻAno Pālua Flanged (Hoʻohui Pālua Flanged, kūlike me ISO 5752):
- Ka lōʻihi o ke alo a i ke alo: Ma kahi o 140mm/210mm
- Ke Kiʻekiʻe Loa (ʻau ʻōlohelohe me ka ʻole o ka mea hoʻoikaika): 410 mm/589mm (concentric/pālua) 2. Nā Kūlana Kumu o ka ASME B16.5 Class 150 Flange (Pili i ka NPS 6" / DN150)
ʻO kēia ke kūlana maʻamau no nā pilina flange valve butterfly (pono ke ʻano Wafer/Lug i kahi flange paipu kūpono, hele mai ke ʻano Double Flanged me kahi flange).
