1. Opening and closing without friction. This function completely solves the problem that the sealing of the traditional valve due to the friction between the sealing surface.

2. Mounted structure. The valve installed on the pipeline can be directly online inspection and maintenance, can effectively reduce the device parking, reduce costs.

3. Single seat design. The problem that the medium in the valve cavity is affected by the abnormal boost is eliminated.

4. Low torque design. Special structural design of the stem, just with a small hand can easily open and close the valve.

5. Wedge seal structure. The valve is provided by the mechanical force of the stem, the ball wedge pressure to the valve seat and seal, so that the valve seal is not affected by the pressure difference in the pipeline, in a variety of operating conditions have a reliable guarantee of sealing performance.

6. Self cleaning structure of sealing surface. When the ball roll off the seat when the fluid in the pipeline along the sealing surface of the sphere into 360 degrees evenly through, not only eliminates the high speed fluid on the seat of local scour, also washed away the sediment on the sealing face, achieve the purpose of cleaning.

Characteristic

Trunnion design - top and bottom support for electric ball valves. The design allows the trunnion closes the valve part, with a full range of pressure off, in the absence of a risk. Valve in the pipeline can not be reversed.

All the concentricity and flatness of the mirror, to ensure smooth operation, easy ball, leak proof.

Double sliding seat O-ring, three each.

All three port costs, the real combination of installation time, and save space.
