An electric actuator is a device that uses an AC/DC power source to drive a valve to open or close by a motor.
In this article, we will give you some guidelines for choosing a COVNA electric actuator.
1. Rotation
COVNA electric actuators have 2 rotations for you to choose from, including 90-degree and 360-degree. The 90-degree version is suitable for controlling ball and butterfly valves, and the 360-degree version is suitable for controlling gate and globe valves. Among them, multi-turn actuator with gearbox is suitable for the ball valve and butterfly valve which needs higher torque.
2. Function
COVNA electric actuator has 5 functions for you to choose, including on/off type, modulating type, intelligent type, explosion-proof type and underwater type actuator. To help you to control locally or remotely.
On/off type actuator just for open or close.
Modulating type actuator for regulating the open/close angle of the valve through the signal.
Intelligent type actuator also for regulating the open/close angle of valve, but it has an LCD display screen for easier control.
Explosion-proof actuator has an excellent explosion-proof performance. To keep the project safe.
Underwater actuator has an underwater shell and the part that has done the underwater treatment to keep the actuator could work well underwater.
3. Voltage & Signal
Although the voltage and signal do not affect the price, the voltage and signal will affect whether the actuator can be used normally.
COVNA electric actuator has a variety of voltage options, such as AC24V, AC110V, AC220V, AC380V, DC12V, DC24V.
At the same time, for the modulating electric actuator, we will provide 3 kinds of signals for you to match the control center. Such as 4-20mA, 0-10V, 1-5V.
