The Pneumatic high-pressure ball valve divides the valve body into three parts along the cross section perpendicular to the valve channel axis at the two seat positions. The entire valve is symmetrical left and right along the central axis of the valve stem. It is mainly used in pipelines to cut off, distribute, and change the direction of medium flow. Its pivot structure accurately positions the center of the sphere under high pressure, and the valve has good operational performance. The electric actuator adopts an integrated structure, which can directly adjust the switch value by inputting 220V power supply. It can also be equipped with a built-in servo module, and can control the operation by inputting control signals (4-20mADC or 1-5VDC) and single-phase power supply.
● Special Design: The entire valve is symmetrical along the central axis of the valve stem, and it is mainly used on pipelines to cut off, distribute, and change the direction of medium flow.
● Good Operational Performance: Its large pivot structure ensures accurate center position of the sphere 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, ensuring 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 blow out 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. When the sphere rotates, the hole aligns or misaligns with the inlet and outlet channels of the valve, thus opening or closing the fluid flow. The pneumatic actuator drives the rotation of the sphere to achieve the opening, closing, and regulation of the fluid. Additionally, internal threads are used to enhance the system's sealing performance.
Our pneumatic high-pressure internal thread ball valve is made from high-quality materials, ensuring the durability and reliability of the product.
