Description
The Failsafe Electric Butterfly Valve Actuator is used to control valves that rotate from 0° to 90° and other similar products, such as butterfly valves, ball valves, dampers, plug valves, louver valves, etc. It uses AC 24V, 110V, 220V AC power and DC24V DC power as the driving power supply. The actuator has its own power supply. It can be widely used in the fields of petroleum, chemical industry, electric power, metallurgy, pharmaceuticals, papermaking, energy, water treatment, shipbuilding, textiles, food processing, building automation, etc. At the same time, it has many advantages such as small size, light weight, exquisite appearance, unique structure, compactness, rapid opening and closing, easy installation, small operating torque, easy operation, digital display of valve position, no maintenance, safe and convenient use, etc.
What is a power-off reset?
A power-off reset actuator is an actuator with special functions. Its main function is to automatically reset or perform specific operations in the event of a power failure. This type of actuator is usually equipped with a reset spring and a solenoid valve. When the control signal is lost or the power is off, the reset spring will return the actuator to the preset position, such as closing the valve, to ensure the safety of the equipment.
Principles and applications
The working principle of the power-off reset actuator is based on the combination of a reset spring and a solenoid valve. When the actuator loses the control signal or the power is off, the reset spring will return the actuator to the "0%" stroke position, usually closing the valve to prevent the medium from continuing to flow, thereby protecting the equipment and system. This function is very important in many critical applications, such as power plants, chemical plants and oil pipelines. The power-off reset actuator can ensure that the valve is automatically closed in an emergency to prevent accidents.

Failsafe actuator
The failsafe is purely an emergency feature and has no other purpose. The actuator is electrically operated in normal use
Charging: The condenser is automatically charged in normal operation.
The battery reset series is a new type of electric actuator with battery reset function. When power failure occurs, it can be preset to "full open", "full closed", "no action", "delay position" and return to a safe position when power is off to protect the safety of equipment or devices.
