"Valavu ya gulugufe 150" nthawi zambiri imakhala ndi magawo awiri ofanana:
- DN150: M'mimba mwake mwa dzina 150mm (yofanana ndi mainchesi 6 mu NPS).
- 150lb / 150 / Kalasi 150: Kuyeza kwa kupanikizika kwa ANSI/ASME Kalasi 150 (pafupifupi 150 psi, yodziwika bwino m'machitidwe wamba aku America, yofanana ndi PN20 ku China/Germany).
1. Miyeso ya Vavu ya Gulugufe ya DN150 / 6"
Mitundu ya ma valavu a gulugufe ndi Wafer, Lug, ndi Double Flanged. Deta yotsatirayi ikufotokoza mwachidule magawo ofunikira kutengera miyezo monga ASME B16.5.
1.1 Mtundu wa Wafer/Lug (Mtundu wa Clip-on/Lug, kulumikizana kwachidule, kumagwirizana ndi ISO 5752):
- Utali wa Maso ndi Maso: 55–57 mm
- Kutalika konse (shaft yopanda chogwirira ntchito): 320–400 mm (yozungulira/yogwira ntchito kwambiri)
- Kukula kwa shaft:≈14 * 14mm
1.2 Mtundu Wokhala ndi Zingwe Ziwiri (Kulumikizana Kokhala ndi Zingwe Ziwiri, kumagwirizana ndi ISO 5752):
- Utali wa Maso ndi Maso: Pafupifupi 140mm/210mm
- Kutalika Konse (shaft yopanda choyatsira): 410 mm/589mm (yozungulira/yawiri) 2. Magawo Oyambira a ASME B16.5 Class 150 Flange (Oyenera NPS 6" / DN150)
Iyi ndi muyezo wa kulumikizana kwa flange ya valavu ya gulugufe (Mtundu wa Wafer/Lug umafuna flange ya chitoliro chofanana, Mtundu wa Double Flanged umabwera ndi flange).

| M'mimba mwake wa nkhope yokwezedwa | 8.50 | 215.9 | Zachizolowezi pa ma flange a RF |
| Kukhuthala kwa Flange (mphindi) | 1.00 | 25.4 | Kuphatikizapo nkhope yokwezedwa |
3. Tchati cha Bolt ya Flange 150 ndi Torque
3.1Mafotokozedwe a Bolt ya Class 150 NPS 6":
- Chiwerengero cha Mabotolo: 8
- M'lifupi mwa Bolt: 3/4"
- Kutalika Koyenera kwa Bolt ya Stud (1/16" RF): Pafupifupi mainchesi 4 (102 (mm)
Mphamvu yolimbikitsira ya flange bolt yopangira ma valve a gulugufe (mutatha kudzola mafuta, kulimbitsa):
| Kukula kwa Vavu | Kukula kwa Bolt | Min Torque (ft-lb) | Max Torque (ft-lb) |
| 5"–8" | 3/4" | 30–40 | 100–120 |
3.2 Masitepe Olimbitsa (Kulimbitsa Mopingasa):
a. Gawo Loyamba: 30% Torque
b. Gawo Lachiwiri: 60% Torque
c. Gawo Lachitatu: 100% Torque
dGawo Lomaliza: Yang'anani mozungulira wotchi/motsutsana ndi wotchi
