1. Fluid resistance is small, and its resistance coefficient is equal to that of the same length.
2. Simple structure, small size, light weight.
3. Close and reliable, the current valve sealing surface material widely used plastic, good sealing, in the
vacuum system has also been widely used.
4. Easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation,
facilitate remote control.
5. Maintenance convenient, simple structure, the sealing ring is generally active, demolition and replacement
are more convenient.
6. In the fully open or fully closed, the ball and valve seat sealing surface and the dielectric isolation, the
media through, will not cause the valve sealing surface erosion.
7. Wide range of applications, from small to a few millimeters diameter, large to a few meters, from high
vacuum to high pressure can be applied.
8. Remote control floating ball valve has its own unique structure of some of the advantages, such as the
switch without friction, seal is not easy to wear, opening and closing torque is small. This reduces the size
of the actuator. Equipped with multi turn electric actuator, can realize the adjustment of the medium and
tight cut off.
