Single-Angle Check Valve

Single-Angle Check 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 check valves — ductile iron resists impact and oil-gas corrosion, while copper internal parts ensure precise sealing and wear resistance. Available in 1.5" and 2" sizes, it precisely matches different flow pipelines of gas stations, guaranteeing "reliable one-way check, long-term stable weather resistance" 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 (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 & Usage
- Exclusive Scenarios for Gas Stations:
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)".
- Usage Steps:
1. Size Matching: Choose 1.5" (conventional) or 2" (high-flow) based on pipeline flow, confirm 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. Maintenance & Inspection: Check valve core opening/closing flexibility quarterly; apply oil-resistant grease if jammed to ensure normal one-way check function.
