Electric valve
Thread Content
Does anyone know anything about electric valves? Do they maintain their position in the event of a power loss? If so, what is the principle?
The actuator of an electric valve contains an electric motor, and the actuation of the actuator is achieved through the rotation of this motor. When the electric actuator loses power, the actuator can no longer rotate and remains in place.
Electric valves are driven by motors; in the event of a power loss, since the motor cannot operate, the valve naturally remains in its current position.
For electric valves, it depends on the configuration; generally, they remain in their current position in the event of a power loss. If they are designed to close or open in such a situation, that will increase the cost, and thus the price will differ.
The principle of an electric valve is that it operates when powered on and shuts off when powered off. When the power runs out, it remains essentially in the same state as before the power loss. Don’t you think it serves to maintain the position! :):):)
When the power to the electric valve is lost, it loses its driving force and remains in place, thanks to its position-holding function. Some electric valves have signal loss protection to maintain their open or closed position
