1. Floating ball valve lip seal seat to ensure good sealing performance, low friction coefficient, small operating torque.

2. Stem anti-flying structure: the stem is downloaded to prevent pressure flying out, and can form metal contact with the valve body after fire to ensure stem sealing.

3. Fire prevention and anti-static device (soft seal floating ball valve).

4. With lock device. In order to prevent valve switch from misoperation, there are locking holes in the fully open and fully closed position of the valve to ensure that the valve is in the correct position.
