KF Flange Pneumatic High Vacuum Ball Valves: Overview, Technical Parameters & Features

The KF Flange Pneumatic High Vacuum Ball Valve refers to a valve whose working pressure is lower than the standard atmospheric pressure, i.e., in a vacuum negative pressure state, so it is usually also called a pneumatic negative pressure ball valve. It is mainly used for on-off control or flow regulation in vacuum systems. The pneumatic vacuum ball valve has very high requirements on materials and cleanliness, because it is necessary to ensure no volatile substances under vacuum, and it has undergone enhanced sealing treatment, which can effectively prevent impurities in the atmospheric environment from entering the valve cavity and contaminating the medium. The pneumatic vacuum ball valve can be installed in any position, and can be used not only in pipeline systems under vacuum conditions but also in normal operation under a certain pressure.

Features of KF Flange Pneumatic High Vacuum Ball Valve

1. It can work normally under high vacuum conditions and also be applied in low-pressure systems, achieving the advantage of being suitable for both positive and negative pressures;

2. The pneumatic vacuum ball valve uses air supply pressure to control the valve, with small driving torque and can be quickly opened and closed in a short time;

3. It can be installed at any position and has various connection methods, which can meet any complex conditions;

4. The pneumatic high vacuum ball valve has a simple structure and excellent sealing performance. Choosing different materials and action forms can adapt to different working conditions;

5. It is widely used in vacuum, dairy products, wine industry, bioengineering, food and chemical fields, and can effectively ensure the sealing performance of the valve.
