In the electric high-pressure ball valve, the vertical cross-section inside the valve body is divided into three parts at two different positions on the valve seat. The entire valve design is symmetrical around the center axis of the valve stem, primarily used for cutting off, distributing, and changing the direction of fluid flow in pipeline systems. Its rotating mechanism can accurately position the ball center under high-pressure conditions, ensuring excellent operational performance. The electric actuator uses an integrated design and requires only a 220V power supply to achieve direct control of the on-off state. Additionally, the valve can be equipped with an internal servo module, operating through control signals (4-20 mA or 1-5VDC) and single-phase power.
● Unique Design: The valve adopts a symmetrical design along the central axis of the valve stem, specially designed for cutting, distributing, and changing the flow direction of the medium in the pipeline.
● Excellent Operational Performance: Thanks to its large rotating shaft structure, the ball can maintain precise center positioning even under high pressure conditions, ensuring smooth operation of the valve.
● Spring Structure: The standard valve seat is designed with a spring that pushes the valve seat to a position close to the sphere, ensuring bidirectional sealing effect at the inlet and outlet.
● Anti-leakage Design: The built-in exhaust valve can discharge the gas inside the valve body to the outside, and the explosion-proof protection structure effectively reduces 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 core 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. This component is controlled by a pneumatic actuator, which performs operations such as opening and closing, and regulating fluid flow through the rotation of the sphere. Additionally, internal threaded connections significantly enhance the system's sealing effect.
