The pneumatic high-pressure ball valve divides the valve body into three parts along a cross-section perpendicular to the valve passage axis at two valve seat positions. The entire valve is designed symmetrically along the central axis of the valve stem. It is mainly used in pipeline systems to achieve the functions of cutting off, distributing, and changing the flow direction of media. Its pivot structure can accurately locate the center position of the ball under high pressure, ensuring excellent operational performance of the valve. The electric actuator adopts a compact integrated design, which can directly adjust the switch value through 220V power input. In addition, it can also be equipped with a built-in servo module to achieve precise control through input control signals (4-20mA or 1-5VDC) and single-phase power supply.
● 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 a valve is a sphere with a central through-hole. The rotation of the sphere precisely aligns or misalignments the through-hole with the inlet and outlet channels of the valve, thereby controlling the flow state of the fluid to achieve opening or closing functions. Under the drive of pneumatic actuators, the sphere rotates, enabling the opening, closing, and adjustment of fluid flow. In addition, the use of internal thread connections effectively improves the sealing performance of the system.
Our pneumatic high-pressure internal thread ball valve is made of high-quality materials to ensure durability and reliability. Its unique design provides excellent sealing performance, effectively preventing leaks and improving system safety.
