The cross-section of the high-pressure pneumatic welded ball valve is perpendicular to the axis of the passage, dividing the valve body into three parts at two seat positions. The entire valve exhibits symmetry on both sides of the center axis of the stem. It is primarily used in pipeline systems to achieve the cutoff, distribution, and redirection of media flow. In high-pressure environments, its rotating mechanism can precisely position the center of the ball, ensuring smooth valve operation. The electric actuator features an integrated design that can directly adjust the switch status by connecting to a 220V power source. Additionally, it can be equipped with an internal servo module for remote operation through control signals 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 flow direction of fluids on pipelines
● Good Operational Performance: Its large pivot structure ensures the 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 of the inlet and outlet.
● Preventing Leakage:The chamber inside the valve body can be discharged to the outside through the built-in discharge valve; The fulcrum of the valve body adopts an 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 offsets the through-hole with the inlet and outlet channels of the valve, thereby controlling the fluid state to achieve opening or closing functions. Driven by pneumatic actuators, the sphere rotates to open, close, and regulate fluid flow. In addition, the internal threaded connection effectively improves the sealing performance of the system.
