In electric high-pressure ball valves, the vertical cross-section inside the valve body is divided into three parts, located at two different positions on the valve seat. The entire valve is designed as a symmetrical structure around the central axis of the valve stem, mainly used in pipeline systems to cut off, distribute, and change the direction of fluid flow. Its rotating mechanism can accurately position the center of the ball under high pressure conditions, ensuring excellent operational performance. The electric actuator adopts an integrated design and only requires a 220V power supply to achieve direct control of the switch state. In addition, the valve can be equipped with an internal servo module that operates through control signals (4-20mA or 1-5VDC) and single-phase power supply.
● Unique Design: The valve adopts the symmetrical design along the center axis of the valve stem, which is specially designed for the cutting, distribution and changing of the flow direction of the medium in the pipeline.
● Excellent Operational Performance: Thanks to its large rotating shaft structure, the ball can maintain accurate center positioning even under high pressure conditions, ensuring smooth valve operation.
● Spring Structure: The standard valve seat is designed with a spring to push the valve seat close to the ball, thus ensuring the two-way sealing effect of the inlet and outlet ports.
● Anti-leakage Design: The built-in exhaust valve can discharge the gas in 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 a valve is a sphere with a central hole. By precisely rotating this sphere, it can align or misalign the channel with the inlet and outlet of the valve, thereby controlling the fluid state to achieve opening or closing. This component is controlled by a pneumatic actuator, which performs operations such as opening, closing, and regulating fluid flow by rotating a sphere. In addition, the internal thread connection significantly enhances the sealing effect of the system.
