Our goal: to be a high-quality manufacturer of industrial control valves, gaining unanimous recognition from new and old customers
Our mission: To fully utilize the effectiveness of industrial control valves to achieve better results
The electric actuator uses AC220 single-phase AC power as its power supply, and receives DC4 to 20mA from DCS, PLC system, and other operators. Standard signals are used to control the actuator to open and close valves or automatically adjust. The electronic control module adopts advanced hybrid integrated circuits, including complete protection functions, which can be controlled locally or remotely. It is designed as a box and sealed with resin casting.
The drive feedback adopts high-performance conductive plastic potentiometers with high accuracy and long service life. It can be combined with various angular stroke adjustment mechanisms to form a high-performance and reliable electric control valve. Therefore, it is widely used in industries such as metallurgy, power generation, petrochemical, paper making, light industry, and environmental protection.
Main features of electric actuators
The actuator is designed with a servo system (no additional servo amplifier is required), which can be operated by simply connecting a DC4 to 20mA (or DC1 to 5V) signal and an AC220V single-phase power supply. The built-in wiring terminal is extremely simple and convenient.
The key component of the actuator, the controller, uses advanced hybrid integrated circuits and is sealed and cast with resin. It has a box shape, small size, and high reliability.
The feedback detection of the driving amount of the electric actuator adopts a high-performance conductive plastic potentiometer with a resolution of<0.4%.
4. It has a self-diagnosis function. When a fault occurs, the indicator light on the controller will immediately send an indication signal.
The state selection switch can be used to set the cutoff signal when the valve core is in a fully open, fully closed, or self-locking state.
6. The state selection switch can be used to set (positive and negative actions).
The input signal can be set to (DC4~20mA or DC1~5V) using a state selection switch.
Adjusting the working zero point (start point) and stroke (end point) is simple and easy.
When suddenly powered off, it can ensure that the valve core is self-locking.
Adopt synchronous belt transmission to effectively reduce noise.
11. Electric actuator protection function, which can implement state self-locking at rated load, immediately start protection when a fault occurs, and can reverse operation to cancel protection.
