Double Motorised ball valve

What is Double Motorised ball valve？

Double Motorised ball valve are similar in principle to traditional ball valves, but have a"C"shaped hemisphere. It is used to control the flow of fluid. These valves are equipped with electric actuators to open and close according to the requirements of the application. Compared with other solenoid ball valves, electric ball valves support high flow and are suitable for fast actions, including emergency shutdown and water hammer prevention.

●Energy-saving and environmental protection: The electric ball valve is driven by a motor, which consumes less energy and causes less pollution than traditional hydraulic or pneumatic drives.

●High degree of automation: The electric ball valve can be used in conjunction with automation control systems such as PLC and DCS to achieve automated control and improve production efficiency and product quality.

●Simple maintenance: The electric ball valve has a simple structure and few parts, making maintenance relatively simple.

●Wide range of application: The electric ball valve is suitable for various media, including high temperature, high pressure, corrosive media, etc.

●Reliable closing: The electric ball valve uses a ball as a closing element, which is reliable and has less leakage

The function of double motorised ball valve

Q: What is the main function of a double motorised ball valve in pipeline systems?

A: The double motorised ball valve is equipped with two independent electric actuators to realise remote switch control and emergency cut‑off functions.It adopts double‑actuator driving structure to control the opening and closing action of the ball, which can realise normal on‑off operation and quick emergency isolation of the pipeline. It can realise position interlock and signal feedback, and monitor the valve working state in real time to ensure the stable operation of the pipeline.

Conclusion: Therefore, the main function of the double motorised ball valve is to realise remote automatic control and emergency safe isolation of the pipeline, providing reliable fluid switching and safety protection for industrial piping systems.

The principle of using double motorised ball valve

Q: What is the working principle of a Double Motorised Ball Valve?

A: Its operation is based on the 90‑degree rotation of the ball driven by double electric actuators. Two actuators can work cooperatively or independently. When receiving the control signal, the actuators output torque to drive the ball to rotate 90 degrees to complete opening or closing. The double‑actuator structure can realise redundant driving. When one actuator fails, the other can still complete the valve action. It feeds back the valve on‑off position signal to the control system at the same time.

Conclusion: Therefore, the operating principle of the double motorised ball valve relies on dual electric actuators to drive ball rotation, achieving automatic fluid switch with redundant drive and position signal feedback for safe and stable pipeline control.

The operating conditions and advantages of double motorised ball valve

Q: What are the common applications and key advantages of double motorised ball valves?

A: This valve is widely used in industrial environments such as oil, gas, chemical, power plant and water treatment industries. It is suitable for pipeline systems requiring high‑reliability remote control, emergency cut‑off and interlock protection. Its key advantages include:

-Redundant Safety Performance: Dual‑actuator redundant drive reduces the risk of valve failure and improves system safety.

-Remote Automatic Control: Supports remote signal control and real‑time position feedback, convenient for centralised system management.

-Emergency Quick Cut‑off: Can rapidly complete valve closing under emergency conditions to cut off medium flow.

-High Reliability: Robust valve body construction adapts to harsh working conditions for long‑term stable service.

-Interlock Compatibility: Easy to connect with DCS and PLC control systems to realise complex process interlock logic.

Conclusion: Therefore, the double motorised ball valve provides a high‑reliability automatic fluid control solution for demanding operating conditions. With advantages such as redundant safety, remote control and emergency shut‑off capability, it is a vital control component for critical industrial pipeline systems.As a leading industrial valve manufacturer, SJ is proud to offer its high‑performance double motorised ball valve solutions, specifically engineered for critical remote control and emergency isolation in oil, gas, and chemical applications. Our double motorised ball valve features an advanced redundant dual‑actuator design fitted on one ball valve body, significantly improving actuation reliability compared to traditional single‑actuator ball valves. This specialised double motorised ball valve ensures stable on‑off operation and reliable emergency cut‑off, allowing operators to remotely control pipeline media without on‑site manual operation. With rugged construction in materials like WCB carbon steel and adherence to strict international standards, SJ delivers the safety, efficiency, and durability your process lines demand。
