HIGH PLATFORM FLANGE BALL VALVE

Detailed

Product features

 

1. Friction free opening and closing: this function completely solves the problem that the sealing essence of traditional valves is affected by the friction between sealing surfaces. 

2 top mounted structure: the valve installed on the pipeline can be inspected and maintained directly online, which can effectively reduce the device and cost.

3. Single seat design: eliminates the problem that the medium in the valve cavity will affect the use safety due to abnormal pressure rise 

4. Low torque design: the valve stem with special structure design can be opened and closed easily with a small handle

5 wedge seal structure: the valve is sealed by the mechanical force provided by the valve stem, so that the sealing performance of the valve is not affected by the change of pipeline pressure difference, and the sealing performance is reliably guaranteed under various working conditions.

6: Cleaning structure of sealing surface: when the ball leans away from the valve seat, the fluid in the pipeline passes through the sealing surface of the ball at 360 ° evenly, which not only eliminates the local scouring of the fluid on the valve seat, but also washes away the accumulation on the sealing surface, so as to achieve the purpose of self-cleaning.
