A current trend is the constant application of various electric actuators in various fields. In terms of operational efficiency and energy saving, the use of automatic control valves is an indispensable part. Manual valves and pneumatic valves commonly used in the traditional industry are inferior to electric valves in terms of installation cost and efficiency.
According to relevant sources in the industry, valves are mostly used to control the flow and flow of various fluids, such as water, oil, chemical liquids, etc., based on parameters such as temperature, pressure, and flow. The control valves commonly used in factories include pressure reducing valves, pneumatic fixed temperature valves, solenoid valve constant temperature systems, proportional control valve constant temperature systems, and temperature control valves. When selecting various types of automatic valves, factors such as the type of heat engine, the required accuracy, the quality of the control valve, the pressure drop, the flow rate and its structure, the failure rate, the manufacturer's credit, and after-sales service should be considered to achieve economical and practical purposes.
As far as the product itself is concerned, the electric valve has the advantages of easy assembly, low failure rate and meeting the automation requirements of the industry, which is a more cost-effective choice for the operator. Because the use of the general traditional pneumatic valve, it is inevitable to have piping, solenoid valve and compressor to match, and the electric valve is driven by the motor, the installation is simple and easy, and the electric valve is installed with the original self-control circuit of the factory, which can save other the costing payment. In addition, the motor drive mode is smooth and open, and there is no shortcoming of excessive instantaneous force, and the failure rate can be greatly reduced.
Many people think that the electric valve is expensive and the cost of use is high. In fact, if the overall calculation, the traditional valve should be equipped with many accessories and pipeline installation, the price is not dominant, but it must bear more maintenance costs.
The future direction of electric actuators.
Industrial operation control mechanism Valve electric actuators are mostly under severe working conditions such as high temperature, high pressure, strong corrosion, high viscosity and high pressure due to the harsh working environment. Therefore, it is also the weakest link in the production control system. If the quality of the electric valve actuator is not good or the operation is improper, it often leads to problems such as the quality of the automation control system being adjusted and the positioning is not accurate. It is better to ensure that electric actuators can work normally in complex environments such as extreme high temperature or low-temperature environment and strong radiation and strong magnetism. It is the research and development direction of electric valve control devices in the future.
