1. Mechanical Float Valve Shutoff
- Purely mechanical float valve system – no electronic signals required.
- Float rises with fuel level; at predetermined capacity, triggers flip plate or valve to close.
- Instantly cuts off incoming fuel supply with high reliability.
- Provides physical protection against overfilling.
2. Automated Sensor & Controller Integration
- Overfill prevention sensors installed at specific high‑level thresholds.
- Sensor sends activation signal to overfill prevention controller when critical level is reached.
- Controller automatically commands delivery system to shut down.
- Provides highly accurate and automated safety layer.
3. Vapor Lock & Pressure Regulation
- Ball float mechanism integrated into vent pipe.
- Float rises to block vent as fuel approaches the top, preventing vapor escape.
- Pressure buildup inside tank safely pushes back against incoming fuel.
- Effectively stops further flow into the tank.
4. Two‑Stage Safety Closure Mechanism
- First stage: initial warning or high‑level alarm, temporarily stops flow with reset option.
- Second stage: ultimate danger level triggers final closure.
- Absolute safety threshold completely seals the tank.
- Prevents any further product entry and ensures zero environmental spillage.
