The vertical cross-section of the electric high-pressure ball valve is divided into three parts along the valve body passage, located at two positions on the valve seat. The entire valve is symmetrically designed around the central axis of the stem. It is mainly used in pipeline systems for cutting off, distributing, and changing the direction of fluid flow. Its rotating mechanism can accurately position the ball center under high-pressure conditions, ensuring excellent operational performance. The electric actuator uses an integrated design, requiring only 220V power to directly adjust the on-off state. Additionally, it can be equipped with a built-in servo module, which operates through control signals (4-20 mA or 1-5VDC) and single-phase power.
● Special Design: The valve is symmetrically designed along the center axis of the valve stem, which is mainly used for cutting, distribution and changing direction of the medium in the pipeline.
● Good Operational Performance: Due to its large rotating shaft structure, the ball can maintain a precise central position even in high pressure environment, ensuring smooth operation of the valve.
● Spring Structure: The standard valve seat adopts a spring structure to push the valve seat near the ball, so as to ensure the bidirectional sealing performance of the inlet and outlet.
● Preventing Leakage: The built-in exhaust valve can discharge the gas in the valve body to the outside, and the explosion-proof protection structure effectively avoids the risk of 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 key component of the valve is a sphere with a central hole. By precisely rotating this sphere, the passage can be aligned or misaligned with the valve's inlet and outlet, thus controlling the fluid state to achieve opening or closing effects. This component is controlled by a pneumatic actuator, which rotates the sphere to perform functions such as opening, closing, and regulating fluid flow. Additionally, internal threaded connections significantly enhance the system's sealing performance.
