Description
Electric Thread Ball Valve combines the traditional threaded ball valve with the automation control capability of an electric actuator, enabling operators to open or close the media in pipelines via electrical signals from a central control room or even from remote locations.
Product Functions and Advantages
The electric thread ball valve converts electrical energy into mechanical rotational torque, driving the ball to rotate 90° to achieve valve opening or closing.
-
Remote Automation: No on-site personnel required; centralized control can be performed via PLC, DCS systems, or remote controllers.
-
Fast Response: The electric actuator can complete full-stroke action within seconds.
-
Safe and Reliable: In hazardous or hard-to-reach areas, electric valves significantly improve operational safety.

Drive and Control
This series can be equipped with an electric ball valve actuator. The actuator housing uses a weather‑resistant aluminum alloy shell and incorporates an overheat protector and a manual override device, ensuring manual operation can be performed during power outages or fault conditions. The actuator is designed with an ISO 5211 standard mounting interface, making assembly and maintenance of the electric actuated ball valve extremely simple. For applications requiring precise flow regulation, a modulating electric actuator can be selected, which accepts a standard 4‑20 mA current signal for proportional control of valve opening.
Installation and Application Scenarios
Thanks to its compact structure and flexible connection options as an NPT ball valve or BSP ball valve, the electric thread ball valve can be easily integrated into various piping systems. It is particularly suitable for:
-
HVAC: On/off control of chilled water and cooling water.
-
Water Treatment: Automatic flushing control for filters and reverse osmosis systems.
-
Industrial Gases: Automated control of nitrogen, compressed air, and other gas pipelines.
-
Agricultural Irrigation: Zoned automatic irrigation control with sensors.
-
Petrochemical: Process line control for various oils and chemical products.
Frequently Asked Questions
Q1: Can an electric threaded ball valve be used for throttling/regulating flow?
A: While it can, we generally do not recommend using a standard on/off electric ball valve for throttling. Prolonged operation in a partially open position can damage the PTFE seat, leading to leakage. For flow regulation, we recommend selecting a modulating electric ball valve with a V‑port ball design.
Q2: What happens to the electric ball valve if there is a power failure?
A: All our actuators are equipped with a manual override mechanism. In the event of a power failure, you can use the supplied hex wrench or handwheel to rotate the valve to a safe position (open or closed). For critical applications, we can also provide a spring‑return fail‑safe actuator.
