Core Differentiation:Exclusive for gas stations, fully made of pure copper (unlike cast iron/alloy foot valves) — resistant to fuel corrosion, safer for static electricity conduction. Covers full sizes: 1", 1.5", 2", 2.5", 3", 3.5", 4", precisely matching all-diameter oil tanks/pipelines in gas stations, achieving "filtration & anti-clogging one-way sealing long-term durability".
1. Material & Core Advantages
- Full Pure Copper Construction: Inherently resists corrosion from gasoline/diesel (no rust, avoids impurity contamination); excellent conductivity to quickly dissipate fuel static electricity (enhances gas station safety); copper’s high ductility/wear resistance keeps filter screens/valve cores from deforming/wearing long-term, lifespan 50% longer than cast iron/alloy alternatives.
2. Key Parameters
- Sizes: 1", 1.5", 2", 2.5", 3", 3.5", 4" (compatible with all gas station oil pipeline interfaces).
- Working Pressure: ≤0.6 MPa (matches normal fuel dispenser/tank pressure).
- Medium: Gasoline, diesel, kerosene, etc.
- Filter Function: Filters rust/impurities in tanks/pipelines to protect fuel dispenser pump precision parts.
3. Application Scenarios, Working Principle & Usage
- Application Scenarios:
1：Underground tank outlets in gas stations: Filters tank bottom sediment, prevents impurities entering pipelines;：
2：Front sections of fuel dispenser pipelines: Traps pipeline impurities, protects internal precision components;
3：Full-range fuel transfer pipelines: 1"–4" sizes cover all pipe diameter needs (from branches to main lines).
- Working Principle:
When immersed in fuel, fuel pressure opens the copper valve core, while the bottom copper filter screens impurities; when fuel transfer stops, the valve core closes automatically via self-weight fuel backpressure — achieving "one-way flow (out only) impurity filtration" (prevents fuel backflow, continuously purifies oil).
- Usage Steps:
1. Size Selection: Choose 1"–4" based on tank/pipeline interface diameter;
2. Sealed Installation: Wrap threaded end with oil-resistant tape, screw into tank outlet/pipeline front (pure copper is easy to handle, tighten moderately for sealing);
3. Regular Maintenance: Unscrew the foot valve quarterly (pure copper components are easy to disassemble), clean filter screen impurities, then reinstall to ensure filtration/one-way sealing performance.
