Applications
The VAX03 Electric Actuator is designed to automate quarter-turn valves and is widely used in:
- Water treatment systems
- Chemical processing
- Oil and gas industries
- Metallurgical plants
- Paper manufacturing
- Food and beverage processing
- Pharmaceutical industries

- Marine and shipbuilding applications
Recommended Valve Sizes
According to the manufacturer’s selection guide, the VAX03 is suitable for the following valve sizes:
Soft-Seated Ball Valves
- DN10 to DN20
Soft-Seated Butterfly Valves
- DN32 to DN65
The final actuator selection should be based on the actual operating torque of the valve. For optimal performance and service life, the manufacturer recommends that the valve operating torque be maintained between 60% and 80% of the actuator’s rated output torque.
