In modern industrial automation, precise flow control is essential. Electric threaded ball valves provide a compact, reliable, and easy-to-maintain solution, combining an electric actuator with a threaded-end ball valve for efficient and automated fluid management.

What Is an Electric Threaded Ball Valve?
An electric threaded ball valve is an automated valve that integrates an electric actuator with a threaded ball valve. The actuator converts electrical signals into mechanical motion, rotating the ball 90° to open or close the flow.
The "threaded" ends (internal or external) allow quick installation and compact integration, making these valves ideal for small-diameter pipelines and applications with limited space.
Commonly used for water, air, oil, and weakly corrosive media, electric threaded ball valves are widely applied in HVAC, chemical processing, water treatment, and industrial machinery.

How It Works?
When the actuator receives a control signal, the internal motor and gear mechanism rotate the valve stem 90°:
Open Position: The ball's bore aligns with the pipeline, allowing smooth fluid flow.
Closed Position: The ball rotates perpendicular to the pipeline, fully blocking the flow.
This 90° rotary action provides fast shut-off, tight sealing, and supports remote or automated operation- essential for modern industrial control systems.

Key Features and Advantages
✔ Automation Control: Remote operation and signal feedback for smart system integration.
✔ Compact Design: Ideal for small pipelines or equipment connections.
✔ Reliable Sealing: PTFE, RPTFE or CPTFE seats ensure zero leakage.
✔ Wide Compatibility: BSP, NPT, and G threads support global installations.
✔ Easy Maintenance: Serviceable without removing the entire pipeline.
