1. It has the advantages of compact structure, small volume and good sealing performance.

2. When fully opened, the sealing surface is completely separated from the flowing medium, thus improving the service life of the valve.

3. Quick opening and closing, small fluid resistance.

4. The overall structure, simple and compact, beautiful appearance.

5. All over-current parts, valves and plug surfaces are lined with polymer materials to meet various working conditions.

6. Fluorine-lined cock valves have large sealing area and high sealing stress, so the operating torque is large. It is precisely because of the large sealing area of the valve, even if the sealing surface is damaged, still can better prevent leakage, maintenance is very convenient.
