B+RS series electric actuator is a standard product introduced by Tianjin Freya Company which is suitable for general occasions. It is mainly used for standard on-off control and modulating control. This product has many unique features and functions.
Over torque protection: The actuator has an over-torque protection measuring mechanism, which can accurately measure the acting force of the valve. When the acting torque exceeds the range, the over-torque switch will act, and the control circuit will stop the operation of the direction and output the signal. When the motor stops, the valve and the actuator will be protected.
Motor overheat protection: There is a thermal relay inside the motor and the motor will automatically cut off the power supply when the motor is abnormally overheated. Electrical protection: The input and output channels are all optically isolated.
Using reasonable integrated compression technology, the powerful system integration function is fully reflected in the wide range of product functions, and fewer electronic components and complex electronic connections are used to ensure that the electric actuator has a high degree of electronic control reliability.
The output shaft of the SD series electric actuator adopts a spline design, and the position of the output arm can be adjusted arbitrarily according to the opening and closing degree and position of the valve, which is convenient for operation.
The actuator is equipped with a hand wheel so that when the power supply fails, the hand wheel can be turned to control the opening and closing actions. When the hand wheel is required to operate, the hand wheel can be turned to the direction of the hand wheel axis.
