How to deal with sudden power failure of pneumatic actuator?
The pneumatic actuator uses AC220 single-phase alternating current as the power supply, receives dc4-20ma from DCS, PLC system and other operators, and controls the actuator to open and close the valve or adjust automatically. The electronic control module adopts the most advanced hybrid integrated circuit, including complete protection function. It can be controlled on site or remotely. It is designed as a box and sealed with resin casting.
The driving feedback adopts high-performance conductive plastic potentiometer with high precision and long service life. It can be combined with various angle travel adjustment mechanisms to form a high-performance and high reliability electric control valve. Therefore, it is widely used in metallurgy, power generation, petrochemical, papermaking, light industry and environmental protection and other industrial sectors.
Main features of pneumatic actuator
1 actuator is designed with servo system (without additional servo amplifier), which can work only by connecting DC4 ~ 20mA (or DC1 ~ 5V) signal and AC220V single-phase power supply. The terminal is set inside, so the connection is very simple and convenient.
The controller, the key part of the actuator, adopts the most advanced hybrid integrated circuit and is sealed and cast with resin. It has the features of box shape, small volume and high reliability.
3. High performance conductive plastic potentiometer is used for feedback detection of driving quantity of pneumatic actuator, and the resolution is less than 0.4%.
It has the function of self diagnosis. When the fault occurs, the indicator light on the controller will send out the indication signal immediately.
5. When the off signal can be set with the state selection switch (the valve core is in full open, fully closed or self-locking state).
6. It can be set with the state selection switch (positive and negative action).
7. The input signal can be set as (DC4 ~ 20mA or DC1 ~ 5V) with the state selection switch.
It is easy to adjust the working zero point (starting point) and stroke (end point).
When the power is cut off suddenly, the valve core can be self locked.
The synchronous belt drive is adopted to effectively reduce the noise.
11 pneumatic actuator delay protection function, when rated load, it can implement state self-locking, when fault occurs, it can start protection immediately, and can reverse operation to cancel delay protection.
