The pneumatic high-pressure ball valve divides the valve body into three parts along the cross-section perpendicular to the axis of the passage in two valve seat positions. The entire valve is symmetrically designed around the center axis of the stem. It is mainly used in pipeline systems to achieve functions such as cutting off, distributing, and changing the direction of the medium flow. Its pivoting structure can accurately position the center of the ball under high pressure, ensuring excellent valve performance. The electric actuator features a compact integrated design and can be directly adjusted for switch values using a 220V power input. Additionally, it can be equipped with an internal servo module to achieve precise control through input control signals (4-20 mA or 1-5VDC) and single-phase power.
● Special Design: The whole valve is symmetrical along the center axis of the valve stem, mainly used for cutting, distribution and changing the direction of the medium flow on the pipeline.
● Good Operational Performance: Its large pivot structure ensures the accurate center position of the ball under high pressure, ensuring good operating performance of the valve.
● Spring Structure: The standard valve seat adopts a spring structure to push the valve seat towards the ball to ensure good two-way sealing performance of the inlet and outlet ports.
● Preventing Leakage:Through the use of built-in discharge valve, the chamber inside the valve body can be discharged to the outside; the pivot of the valve body 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 state of the fluid to achieve opening or closing functions. Driven by a pneumatic actuator, the sphere rotates to open, close, and regulate the flow of the fluid. Additionally, internal threaded connections effectively enhance the system's sealing performance.
