1. Level-based Filling: Utilizes negative pressure and low vacuum filling to effectively prevent foaming of the liquid being filled.

2. Long lifespan: The filling valve has a precise structure with fewer seals, ensuring reliability and durability.

3. Spray-type Filling: During filling, the liquid flows down the inside wall of the container, effectively preventing foam formation caused by liquid impact on the bottle bottom.

4. Low Bottle Breakage: Utilizes an elastic bottle cradle structure that gently supports bottles during filling, effectively reducing breakage.

5. Bottles Only: Bottles with defects, including missing or malformed bottle openings, are not filled, thereby enhancing the quality of the filled product.

6. Maintenance: The filling valve has a simple structure, making it easy to disassemble and clean.
