Single-Angle Check Valve

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 (e.g., pressure fluctuations during dispenser start-stop). It won’t crack/deform in outdoor/underground installations, with a service life 40%+ longer than ordinary cast iron valves.
- Copper Internal Parts (Valve Core/Seal Components): Copper’s self-lubrication and fuel corrosion resistance make valve core opening/closing smoother, sealing surfaces wear slower, and no leakage occurs after long-term use (perfect for gasoline, diesel, etc.).

2. Key Specifications
- Sizes: 1.5", 2" (compatible with standard pipeline interfaces of gas station fuel dispensers).
- 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
1： One-way check of dispenser main oil circuit: Prevents fuel from flowing back to underground tanks. Ductile iron resists oil-gas corrosion, and copper internal parts ensure reliable check sealing during frequent start-stops (dozens of times daily).
2： Matching different flow pipelines: 1.5" for conventional flow dispensers, 2" for high-flow filling equipment. Dual sizes cover multiple refueling scenarios in gas stations, avoiding "flow restriction (small valve)" or "cost waste (large valve)".
