Main characteristics and application of electric V type flanged ball valve:

V type electric control valve electric | V type ball valve as the ball core with V type structure, with the shearing of the seat. So the suspension in papermaking, chemical, metallurgical and other industrial enterprises containing small particles and fiber to the control parameters of the process, automatically adjust the fluid especially for pulp and paper production process of paper pulp, white water, black liquor, white liquor and other suspended particles concentration, turbidity and slurry fluid medium.
1, the V notch core and metal valve seat before shearing, especially for fibers, small solid particles, slurry and other media;
2, worm drive V shaped cut-off ball valve also has the ability to adjust and reliable positioning, flow characteristics as approximate percentage, adjustable range;
3, the use of leaf spring loaded movable seat structure, seat and ball core will not produce blocking or separation problems, reliable sealing, long service life.

Electric V type regulating ball valveProduct features
1, with elastic load pressure auxiliary seat, to ensure that the valve seat and the ball core from the end to the end of the close contact
2, with an integral body structure, there is no potential leakage potential
3, with equal percentage characteristics, has a wide range of control and a particularly stable control process, can be widely used in a variety of processes
4, the stem and ball core using involute spline connection, when the tooth profile is loaded, the radial force on the tooth can play the role of automatic centering, and the force of each tooth uniform, so that the high strength, long life
