The electric high-pressure ball valve is divided into three parts along the vertical cross-section of the valve body channel, at two positions on the valve seat. 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 fluid in pipelines. Its rotating structure can precisely 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 operates through control signals (4-20 mA or 1-5VDC) and single-phase power.
● Special Design: The whole valve is symmetrical along the center axis of the valve stem, mainly used for cutting, distribution and changing the direction of medium flow on the pipeline.
● Good Operational Performance: Its large pivot structure ensures the accurate center position of the ball under high pressure, ensuring good operating performance of the valve.
● Spring Structure: The standard valve seat adopts spring structure to push the valve seat towards the ball, ensuring good two-way sealing performance of the inlet and outlet ports.
● Preventing Leakage: Through the use of built-in discharge valve, the chamber inside the valve body can be discharged to the outside; the valve body adopts 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 the valve is a sphere with a central through-hole. The rotation of the sphere precisely aligns or misaligns the through-hole with the inlet and outlet channels of the valve, thus controlling the fluid state to achieve opening or closing functions. Driven by a pneumatic actuator, the sphere rotates to open, close, and regulate fluid flow. Additionally, internal threaded connections effectively enhance the system's sealing performance.
