Notes:
- Actuator: A device that controls a valve or other mechanism.
- Normally closed (NC): The valve is in the closed position by default, when the actuator is not powered.
- Normally open (NO): The valve is in the open position by default, when the actuator is not powered.
- Stroke: The distance the actuator moves the valve.
- Shutter force: The force the actuator applies to the valve.
- Micro switch: A small switch that is activated by the actuator.
- IP rating: A measure of the protection against dust and water.
- TÜV: A German certification organization.
