What Are The Structural Characteristics Of Stainless Steel Three-way Ball Valve?

2 Piece Ball Valve and flange gate valve are valves of the same type, the difference is that its closing part is a sphere, which rotates around the center line of the valve body to achieve a valve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium.

The working principle of the stainless steel three-way ball valve is to make the valve unblocked or blocked by rotating the valve. The ball valve is light and small in size, can be made into a large caliber, has reliable sealing, simple structure, and convenient maintenance. The sealing surface and the spherical surface are often in a closed state and are not easily eroded by the medium. It is widely used in various industries.

The stainless steel three-way ball valve is a relatively new type of ball valve. It has some advantages of its own structure, such as no friction when switching, the seal is not easy to wear, and the opening and closing torque is small. This can reduce the specifications of the actuator. Equipped with a multi-turn electric actuator, it can achieve the adjustment and strict shutoff of the medium. It is widely used in working conditions that require strict shutoff, such as petroleum, chemical industry, and urban water supply and drainage.

What are the structural characteristics of stainless steel three-way ball valves?

1. Opening and closing without friction: completely solves the problem of traditional valves affecting sealing due to mutual friction between sealing surfaces;

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

3. Single valve seat design. It solves the problem of abnormal pressure increase in the valve cavity medium affecting the safety of use;

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

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 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. Self-cleaning structure of the sealing surface. When the ball tilts away from the valve seat, the fluid in the pipeline passes evenly along the ball sealing surface at 360°, which not only cleans the local scouring of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface, achieving the purpose of self-cleaning.
