ZKRR electric O type cut off ball valve 
 The main characteristic is its own compact, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical often in the closed state, is not easy to be medium erosion, easy operation and maintenance and for general working media such as water, solvent, acid and gas, but also for the poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, has been widely used in various industries. Ball valve can be a whole, can also be combined. 
 Advantage 
 A. Fluid resistance is small, full bore ball valve basic flow resistance. 
 Two. Simple structure, small size and light weight. 
 3. Close and reliable. It has two sealing surface, and the valve sealing surface material widely used kinds of plastic, good sealing, can be completely sealed. Also been widely used in the vacuum system. 
 4. Easy to operate, opening and closing rapidly, from fully open to fully closed as long as the rotation of 90 °, to facilitate remote control.
