The pneumatic high-pressure ball valve divides the valve body into three parts along the cross-section perpendicular to the axis of the valve body passage, at two valve seat positions. The entire valve is symmetrical about the center axis of the stem. It is mainly used for cutting off, distributing, and changing the direction of flow in pipelines. Its pivoting structure can accurately position the ball center under high pressure, ensuring good operational performance. The electric actuator uses an integrated structure and can directly adjust the switch value by inputting 220V power. It can also be equipped with an internal servo module, which can be controlled by inputting control signals (4-20mA or 1-5VDC) and a single-phase power supply.
● 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 this valve is a sphere with a through hole in the middle. When the sphere rotates, the through hole aligns or misalignments with the inlet and outlet channels of the valve, thereby achieving fluid opening or closing. By using pneumatic actuators to drive the rotation of the sphere, fluid can be opened, closed, and regulated, while utilizing internal thread connections to improve the sealing performance of the system.
