Q41F-16P three-piece flanged ball valve,three-piece flanged ball valve. flanged ball valve, ball valve

The valve seat of the Q41F three-piece flanged ball valve adopts an elastic sealing structure, ensuring reliable sealing and easy opening and closing. The valve stem adopts a bottom-mounted structure with an inverted seal. When the valve cavity abnormally increases in pressure, the valve stem will not be pushed out. The valve body casting adopts the advanced technology introduced from Taiwan, with a reasonable structure and beautiful shape. Drive mode: manual, electric, pneumatic. A 90° switch positioning mechanism can be set up and locked as needed to prevent misoperation.

Working principle of Q41F three-piece flanged ball valve:

The three-piece flanged ball valve is a type of valve that uses a ball with a circular channel as the opening and closing component. The ball rotates with the valve stem to achieve the opening and closing actions. The opening and closing part of a ball valve is a perforated sphere that rotates around an axis perpendicular to the channel, thereby achieving the purpose of opening and closing the channel. Ball valves are mainly used to cut off or connect the medium in pipelines and equipment, and can also be used for the regulation and control of fluids. Ball valves have low fluid resistance, simple structure, small volume, light weight, tight and reliable performance, convenient operation and maintenance, and will not cause erosion of the valve sealing surface. They have a wide range of applications.

Product Features of Q41F Three-piece Flanged Ball Valve

1. Single-seat design. The problem that the medium in the middle cavity of the valve was affected in terms of usage safety due to abnormal pressure increase has been eliminated.

2. Low-torque design. The valve stem with a special structure design can be easily opened and closed with just a small handle.

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

4. Three-piece structure. Valves installed on pipelines can be directly inspected and maintained online, which can effectively reduce the downtime of the equipment and lower costs.

5. Wedge-shaped sealing structure. Valves are sealed by the mechanical force provided by the valve stem, which presses the ball wedge onto the valve seat. This ensures that the sealing performance of the valve is not affected by changes in pipeline pressure difference, and its sealing performance is reliably guaranteed under various working conditions.

6. Self-cleaning structure of the sealing surface. When the ball tilts off the valve seat, the fluid in the pipeline passes uniformly at 360° along the sealing surface of the ball. This not only eliminates the local scouring of the valve seat by the high-speed fluid but also washes away the accumulated substances on the sealing surface, achieving the purpose of self-cleaning.
