Emergency Shut-Off Valve

1. Materials & Core Advantages
-Ductile Iron Valve Body: Strength surpasses ordinary cast iron, resisting long-term oil-gas erosion (e.g., corrosive environment from gasoline volatilization) and pipeline impact (dispenser start-stop or accidental collision). 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. It responds sensitively during emergency shut-off and no leakage occurs after long-term use (perfect 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
- Female Thread Style: Adapts to gas station pipelines with *female thread interfaces* (e.g., internal connection pipelines of dispenser hosts), directly screwed in for convenient installation and fewer adapters.
- Male Thread Style: Matches pipelines with *male thread interfaces* (e.g., some oil tank output pipes), no additional reducing/adapting needed, and sealing is more direct.
- Style with Movable Joint: Deals with complex pipeline layout scenarios (e.g., angle deviation between dispensers and oil tanks, inconsistent joint types). The movable joint flexibly adjusts connection angles and is compatible with multiple interface types, reducing installation adaptation difficulty.
