The cross-section of the high-pressure pneumatic welded ball valve is perpendicular to the axis of the passage, and the valve body is divided into three parts at two seat positions. The entire valve exhibits perfect symmetry on both sides of the center axis of the stem. It is mainly used in pipeline systems to achieve the cutoff, distribution, and redirection of media flow. In high-pressure environments, its rotating mechanism can precisely locate the center of the ball, ensuring stable operation of the valve. The electric actuator uses an integrated design and can be directly connected to a 220V power source to adjust the on-off state. Additionally, it can be equipped with an internal servo module for remote operation through control signals and single-phase power.
● Unique Design: The valve is known for its symmetry along the center axis of the valve stem and is mainly used to cut off, distribute and change the direction of flow in pipelines.
● Excellent Operating Performance: Thanks to its large pivot structure, the ball can maintain a precise central position even in high pressure environment, thus ensuring excellent operating performance of the valve.
● Spring Structure: The standard valve seat is designed with a spring to push the valve seat close to the ball, ensuring excellent bidirectional sealing performance of the inlet and outlet ports.
● Anti-leakage Design: The internal chamber of the valve body can be discharged to the outside through the built-in discharge valve; at the same time, the valve body shaft is designed with explosion-proof protection to effectively avoid leakage problems.

Q1:What is the main suitable of this valve?
This product is especially suitable for steel, aluminum, fiber, small solid particles, pulp, coal ash, petroleum gas and other media.
Q2:What mechanical principle is used?
The core component of the valve is a sphere with a central through-hole. The precise rotation of the sphere can accurately align or misalign the through-hole with the inlet and outlet channels of the valve, thereby controlling the fluid state to achieve the opening or closing function of the valve. It is driven by a pneumatic actuator, which opens, closes, and regulates the flow of fluid through the rotation of the sphere. Additionally, the internal threaded connection effectively enhances the system's sealing performance.
