Product features:
1. The sealing structure of the valve seat shall be elastic with pretension, and the upper and lower sealing seat shall be sealed at the same time. The seat and seal are always face to face.
2. Seat has self-cleaning function and is not directly washed by airflow during valve opening or closing. Seats shall be made of lubricated, non-wear-resistant material.
3. The failure of the valve actuator will not affect other parts of the valve. Repair and replacement can be carried out without removing the valve.
