3. Advantages of Fixed Ball Balve and Floating Ball Valve
Compared with the floating ball valve, when the Fixed ball valve works, all the force generated by the fluid pressure in front of the valve on the ball is transmitted to the bearing, and the ball will not move to the valve seat, so the valve seat will not bear excessive pressure, so it is fixed The ball valve has small torque, small valve seat deformation, stable sealing performance and long service life, and is suitable for high pressure and large diameter occasions.
