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

2. Long lifespan: The filling valve has a precise structure with minimal sealing parts, ensuring reliability and durability.

3. Spray-type Filling: The liquid flows down the inner wall of the container during filling, effectively inhibiting the foaming caused by the liquid impacting the bottom of the bottle.

4. Less Bottle Damage: Utilizes an elastic bottle support structure that gently supports bottles during filling, effectively reducing breakage.

5. Bottles Only: Bottles with defects or damaged openings are not filled, thereby enhancing the quality of the filled product.

6. In terms of maintenance: The filling valve has a simple structure, making it easy to disassemble and clean.
