Structural Characteristics of Stainless Steel Three-Way Ball Valve

The closing part of the stainless steel Three-Way Ball Valve is a sphere. The sphere rotates around the center line of the valve body to achieve opening and closing.

Structural features of stainless steel three-way ball valve:

1. Open and close without friction: completely solve the problem of traditional valves affecting the sealing due to mutual friction between the sealing surfaces;

2. Top-mounted structure: The valve installed on the pipeline can be directly inspected and repaired online, which can effectively reduce device shutdown and reduce costs. This type of valve should generally be installed horizontally in the pipeline;

3. Single valve seat design. Eliminates the problem that the medium in the valve cavity affects the safety of use due to abnormal pressure increase;

4. Low torque design. The valve stem with special structure design can be opened and closed easily with only a small handle;

5. Wedge-shaped sealing structure. The valve relies on the mechanical force provided by the valve stem to press the ball wedge onto the valve seat to seal, so that the sealing performance of the valve is not affected by changes in pipeline pressure, and the sealing performance is reliable under various working conditions;

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

Three-Way Ball Valve

Stainless steel three-way ball valve has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length

2. Simple structure, small size and light weight

3. It is tight and reliable. At present, the sealing surface material of the Ball Valve is widely used in plastics, with good sealing performance, and it has also been widely used in vacuum systems.

4. Convenient operation, rapid opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for remote control

5. Convenient maintenance, simple structure of the ball valve, the sealing ring is generally movable, it is more convenient to disassemble and replace

6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes, it will not cause erosion of the valve sealing surface

7. A wide range of applications, from small to several millimeters, as large as several meters, and can be applied from high vacuum to high pressure

The installation and maintenance of stainless steel three-way ball valve should pay attention to the following matters:

1. Leave the position of the valve handle to rotate;

2. Cannot be used for throttling;

3. The ball valve with drive mechanism should be installed upright.
