"Valve ea serurubele sa 150" hangata e kenyelletsa liparamente tse peli tse tloaelehileng:
- DN150: Bophara ba lebitso la 150mm (bo lekanang le lisenthimithara tse 6 ho NPS).
- 150lb / 150 / Sehlopha sa 150: Tekanyo ea khatello ANSI/ASME Sehlopha sa 150 (hoo e ka bang 150 psi, e tloaelehileng litsamaisong tse tloaelehileng tsa Amerika, e lekanang le PN20 Chaena/Jeremane).
1. Litekanyo tsa Valve ea Serurubele ea DN150 / 6"
Mefuta ea li-valve tsa serurubele e kenyelletsa Wafer, Lug, le Double Flanged. Lintlha tse latelang li akaretsa liparamente tsa bohlokoa ho latela maemo a kang ASME B16.5.
1.1 Mofuta wa Wafer/Lug (Mofuta wa Clip-on/Lug, khokahano e kgutshwane e tlwaelehileng, e dumellana le ISO 5752):
- Bolelele ba ho shebana lifahleho: 55–57 mm
- Bolelele ka Kakaretso (sekoti se se nang letho ntle le actuator): 320–400 mm (tshebetso e tebileng/e phahameng)
- Boholo ba mokoti:≈14 * 14mm
1.2 Mofuta oa Li-Flanged tse Habeli (Khokahano ea Li-Flanged tse Habeli, e latela ISO 5752):
- Bolelele ba ho shebana ka lifahleho: Hoo e ka bang 140mm/210mm
- Bolelele ka Kakaretso (moqomo o se nang letho o se nang actuator): 410 mm/589mm (o kobehileng/o habeli) 2. Liparamithara tsa Motheo tsa Flange tsa ASME B16.5 Class 150 (E sebetsa ho NPS 6" / DN150)
Ena ke tekanyetso bakeng sa dikgokelo tsa flange tsa di-valve tsa serurubele (Mofuta wa Wafer/Lug o hloka flange ya phaephe e tsamaellanang, Mofuta wa Double Flanged o tla le flange).
