AA Globe Valve
AA Globe Valve (For Gas Station Fuel Dispensers)
Core Differentiation:Designed exclusively for gas station fuel dispensers, with ductile iron valve body + copper internal parts. Unlike ordinary cast iron/all-steel globe valves — ductile iron resists impact and oil-gas corrosion, while copper internal parts ensure precise sealing and wear resistance. The 1.5" size precisely matches gas station pipeline flow, guaranteeing "reliable on-off, long-term durability" for fuel dispenser oil circuits.
1. Materials & Core Advantages
- Ductile Iron Valve Body: Strength surpasses ordinary cast iron, resisting long-term oil-gas erosion in gas stations and pipeline impact. It won’t crack/deform in outdoor/underground installations, with a service life 30%+ longer than ordinary cast iron valves.
- Copper Internal Parts (Valve Core/Seals): Copper’s self-lubrication and corrosion resistance make valve core switching smoother, sealing surfaces wear slower, and no oil leakage occurs after long-term use (suitable for gasoline, diesel, etc.).
2. Key Specifications
- Size: 1.5" (compatible with standard 1.5" interfaces of gas station fuel dispenser pipelines).
- Working Pressure: ≤0.6 MPa (covers fuel dispenser’s normal working pressure range).
- Medium Compatibility: Gasoline, diesel, kerosene, etc.
- Temperature Range: -20℃ ~ +60℃ (adapts to day-night/seasonal temperature changes in gas stations).
3. Application Scenarios & Usage
- Exclusive Scenarios for Gas Stations:
1：Main oil circuit switch of fuel dispensers: Controls fuel on-off between dispensers and underground tanks. Ductile iron resists oil-gas corrosion, and copper internal parts ensure reliable sealing during frequent switching (dozens of times daily).
2：Pipeline branch control: The 1.5" size matches medium-flow pipelines in gas stations for precise branch control, avoiding "flow restriction" (small valves) or "cost waste" (large valves).
- Usage Steps:
1. Pipeline Matching: Confirm 1.5" interface matches dispenser/tank pipelines, clean oil stains.
2. Sealed Installation: Wrap threaded ends with oil-resistant tape, screw clockwise into pipeline (tighten ductile iron moderately for sealing; avoid damaging copper parts with excessive force).
3. On-Off Operation: Rotate the handwheel clockwise to close, counterclockwise to open; check switching smoothness quarterly, apply oil-resistant grease if jammed.
