Product introduction of three piece flange ball valve:

The valve seat of three piece flange ball valve produced and sold by Wo valve (Shanghai) Co., Ltd. adopts elastic sealing structure, which has reliable sealing and easy opening and closing. The valve rod adopts a bottom mounted structure with inverted seal. When the valve chamber is abnormally pressurized, the valve rod will not be rushed out. The valve body casting adopts the advanced technology introduced from Taiwan, with reasonable structure and beautiful shape. Driving mode: manual, electric and pneumatic. A 90 ° switch positioning mechanism can be set to lock as needed to prevent misoperation.

Working principle of three piece flange ball valve:

Three piece flange ball valve is a valve that uses a ball with a circular channel as the opening and closing part, and the ball rotates with the valve stem to realize the opening and closing action. The opening and closing part of the ball valve is a sphere with holes, which rotates around the axis perpendicular to the channel, so as to achieve the purpose of opening and closing the channel. The ball valve is mainly used to cut off or connect the pipeline and equipment medium, and can also be used for fluid regulation and control. The ball valve has the advantages of small fluid resistance, simple structure, small volume, light weight, compact and reliable, convenient operation and maintenance, no erosion of the valve sealing surface and wide application range.

Features of three piece flange ball valve:

1. Single seat design. The problem that the medium in the cavity of the valve affects the use safety due to abnormal pressure rise is eliminated.

2. Low torque design. The valve stem with special structural design can be opened and closed easily with only a small handle.

3. There is no friction between opening and closing. This function completely solves the problem that the sealing surface of traditional valves is affected by mutual friction between sealing surfaces.

4. Three piece structure. The valve installed on the pipeline can be directly inspected and repaired online, which can effectively reduce the shutdown of the device and reduce the cost.

5. Wedge seal structure. The valve is sealed by pressing the ball wedge onto the valve seat by the mechanical force provided by the valve stem, so that the tightness of the valve is not affected by the change of pipeline differential pressure, and the sealing performance is reliably guaranteed under various working conditions.

6. Self cleaning structure of sealing surface. When the ball tilts away from the valve seat, the fluid in the pipeline passes through the sealing surface of the ball at 360 °, which not only eliminates the local scouring of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface, so as to achieve the purpose of self-cleaning
