Modulating Electric Actuator Operated Ball Valve

An electric actuated ball valve combines a standard ball valve with an electric actuator, allowing the valve to open or close automatically when a control signal is received, eliminating the need for manual operation 
. These valves are widely used in industrial automation, chemical processing, water treatment, and HVAC systems due to their reliability, precision, and integration with control systems like PLCs or SCADA 

Electric actuators rotate the ball inside the valve body 90 degrees (quarter-turn) to switch between fully open and fully closed positions . On/off actuators use internal cams and limit switches to stop the motor once the valve reaches the desired position. Some actuators are multi-voltage and can automatically adjust to the input voltage, while torque ratings vary from compact 17Nm units to high-power 600Nm actuators for larger valves .

• Two-way ball valves: Standard on/off flow control.
• Three-way ball valves: L-port or T-port configurations for fluid diversion or mixing 
• Full bore valves: Allow maximum flow with minimal pressure drop, suitable for heavy-duty applications 
• V-notch ball valves: Provide precise throttling and flow modulation 

Electric actuated ball valves are available in stainless steel, UPVC, and other corrosion-resistant materials, making them suitable for high-pressure, chemical, and food-grade applications 
. Most valves and actuators follow the ISO 5211 mounting standard, ensuring compatibility between valve bodies and actuators 
. Certifications such as ATEX, CE, RoHS, SIL, FDA, and ISO9001 are often available for industrial compliance 

• Automated operation reduces labor and improves safety in hazardous environments 
• Precise flow control allows accurate throttling and modulation 
• Remote operation enables integration with smart control systems 
• Durability and reliability with corrosion-resistant materials and high-performance actuators 
• Reduced maintenance and lower risk of leaks compared to manual valves
