1. In the valve switching process, the valve body sealing surface does not have any contact with the slide sealing surface, therefore, the sealing surface has no friction, wear, long service life of the valve and small switching torque;

2. Valve maintenance, do not need to remove the valve from the pipeline, just open the bottom cover of the valve, replace a pair of slide, maintenance is very convenient;

3. The valve body and the cock are reduced or full diameter, the medium has no flow resistance through the valve, and the pipe can be cleaned through the ball, to overcome the shortcomings of the reduced diameter valve;

4. The full-diameter and reduced-diameter warlord body cavity is plated with hard chrome, the sealing area is hard and smooth;

5. The elastic seal on the slide sheet is made of fluorine rubber and moulded in the groove on the surface of the slide sheet. Metal to metal seal with fire protection function as the backing of the elastic seal;

6. The valve has an automatic release device (optional) to prevent abnormal pressure boost in the valve chamber and test the effect of the valve after the valve is completely closed;

7. The valve switch indicator is synchronized with the switch position, which can accurately display the switch status of the full diameter gear drive.
