The cross-section of the high-pressure pneumatic welded ball valve is perpendicular to the channel axis, and the valve body is divided into three parts at two valve seat positions. The entire valve exhibits perfect symmetry on both sides of the central axis of the valve stem. It is mainly used in pipeline systems to achieve the cutting, distribution, and redirection of medium flow. In high-pressure environments, its rotating mechanism can accurately locate the center of the sphere, ensuring the smooth operation of the valve. The electric actuator adopts an integrated design and can be directly connected to a 220V power supply to adjust the switch state. In addition, an internal servo module can be equipped to achieve remote operation through control signals and single-phase power supply.
● Unique Design: This valve is known for its symmetry along the central axis of the valve stem and is mainly used to cut, distribute, and change the flow direction in pipelines.
● Excellent Operating Performance: Thanks to its large pivot structure, the ball can maintain precise center position even in high-pressure environments, ensuring excellent operational 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 a valve is a sphere with a central through-hole. The precise rotation of the sphere can align or offset 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 pneumatic actuators and opens, closes, and regulates fluid flow through the rotation of a sphere. In addition, the connection method of internal threads effectively enhances the sealing performance of the system.
