main features
1. The flexible movable metal valve seat structure with cylindrical spring or waveform spring preloading is adopted, and the sealing preload force is designed reasonably and the opening and closing are flexible, effectively ensuring the reliability of the seal.
2. The valve stem with a special structural device not only ensures that there will be leakage at the filling point, but also prevents the valve stem from coming out.
3. According to user needs, the structure can be designed to adapt to media such as dust (including solid particles) and slurry, making the ball valve more wear-resistant and heat-resistant.
4. It has fire and static electricity prevention functions.
5. This structural ball valve should be used according to the specified flow direction.
