 Wide flange ball valve Features: 

 1. Fluid resistance, the drag coefficient with the same length of pipe equal. 

 2. Tight, reliable, current valve sealing surface material widely used plastic, sealing well. 

 3. Easy to operate, opening and closing rapidly, fully open to fully closed as long as from the rotation 90 °, to facilitate the remote control. 

 4. Easy maintenance, simple ball valve, seals are generally active, are relatively easy to replace demolished. 

 5. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, the medium through, it will not cause erosion of the valve sealing surface
