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 the two valve seat positions. The entire valve exhibits 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 ball center, ensuring smooth operation of the valve. The electric actuator uses an integrated design and can be directly adjusted to switch status by connecting to a 220V power source. Additionally, it can be equipped with an internal servo module for remote operation through control signals and single-phase power.
● Special Design: The entire valve is symmetrical along the central axis of the valve stem, mainly used for cutting, distributing, and changing the flow direction of fluid on the pipeline.
● Good Operational Performance: Its large pivot structure ensures the precise center position of the ball under high pressure, ensuring good operational performance of the valve.
● Spring Structure: The standard valve seat adopts a spring structure, which pushes the valve seat towards the sphere to ensure good bidirectional sealing performance at the inlet and outlet.
● Prevent Leakage:The chamber inside the valve body can be discharged to the outside through the built-in discharge valve; The valve body pivot adopts explosion-proof protection structure, effectively preventing leakage.

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 rotation of the sphere precisely aligns or misaligns the through-hole with the inlet and outlet channels of the valve, thus controlling the fluid state to achieve opening or closing functions. Driven by a pneumatic actuator, the sphere rotates to open, close, and regulate fluid flow. Additionally, internal threaded connections effectively enhance the system's sealing performance.
