The pneumatic high-pressure ball valve divides the valve body into three parts along a cross-section perpendicular to the axis of the valve passage at two seat positions. The entire valve is designed with symmetrical features around the centerline of the stem. It is primarily used in pipeline systems to achieve functions such as shut-off, distribution, and changing the direction of the medium flow. Its pivoting structure can precisely position the ball's center under high pressure, ensuring excellent operational performance. The electric actuator features a compact integrated design that allows direct adjustment of the switch value using a 220V power input. Additionally, it can be equipped with an internal servo module to achieve precise control through input control signals (4-20mA or 1-5VDC) 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 direction of medium flow on pipelines.
● Good Operational Performance: Its large pivot structure ensures accurate 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.
● Preventing Leakage: By using the built-in discharge valve, the chamber in the valve body can be discharged outward; The pivot adopts an anti explosion 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 aligns or misaligns the through-hole precisely with the inlet and outlet channels of the valve, thus controlling the flow state of the fluid to achieve opening or closing functions. Driven by a pneumatic actuator, the sphere rotates, thereby enabling the opening, closing, and flow regulation of the fluid. Additionally, the use of internal thread connections effectively enhances the system's sealing performance.
