An electric actuator, also known as an electric actuator, is a driving device that can provide linear or rotational motion. It utilizes a certain driving energy source and operates under a certain control signal. The actuator uses liquid, gas, electricity, or other energy sources and converts them into driving force through motors, cylinders, or other devices. There are three basic types of drive: Part Turn, Multi Turn, and Linear.
During the use of valves, there are often some troublesome problems, such as whether the valve is tightly closed or not. What should be done? The following are several methods for dealing with internal leakage in control valves.
Only when the regulating valve resonates can there be energy superposition that produces a strong noise of more than 100 decibels. Some are characterized by strong vibration and low noise, while others are characterized by weak vibration and very high noise; Some have high vibration and noise.
Electric valve actuator, also known as valve electric device, is an actuator that uses electricity as the energy source in the control system. It receives electrical signals from regulating instruments, changes the amount of manipulation according to the size of the signal, and changes the amount of material or energy of the input or output control object to achieve automatic program adjustment.
Operating torque The operating torque is the most important parameter for selecting an electric actuator. The output torque of the electric device should be 1.2 to 1.5 times the maximum torque of the valve.
The valve electric device is one of the devices for operating the valve and connecting the valves. The device is powered by electrical power and its motion can be controlled by the magnitude of the stroke, torque or axial thrust. Due to the working characteristics and utilization of the valve electric device, it depends on the type of valve, the working specifications of the device and the position of the valve on the pipeline or equipment. Therefore, it is important to grasp the correct choice of the valve electric device; considering the prevention of overload (working torque is higher than the control torque) becomes a crucial part.
