Vacuum Filling Valve for Precision Liquid Dispensing Under Vacuum Conditions
Description
The Vacuum Filling Valve is designed for precision liquid dispensing and filling processes under vacuum conditions. It enables direct metered liquid injection without the need for traditional vacuum cup systems, improving process efficiency and dosing consistency.
Product Feature
1. Direct metered liquid filling under vacuum conditions without traditional vacuum cup systems.
2. Isolates the dispensing system from vacuum influence, improving dosing stability and accuracy.
3. Conical sealing design ensures reliable vacuum-tight performance and long service life.
4. Protects metering pumps, valves, and pipelines from vacuum-related stress.
5. Available in customized pipe diameters, lengths, and configurations to meet different process requirements.
6. Suitable for integration with ceramic metering pumps and automated dispensing systems.

Working Principle
1. Place the workpiece (such as bottles, pouch batteries, etc.) into the vacuum chamber.
2. The vacuum pump evacuates the chamber.
3. Air inside the container is removed.
4. The filling valve opens.
5. A ceramic metering pump delivers a precise amount of liquid to the filling valve.
6. Under pressure differential, the liquid rapidly enters the container.
7. After filling is complete, the valve closes.
