The Difference between Electro-magnetic Valves and Electric Valves
Valves are mechanical devices designed to regulate the flow of liquids, gases and other substances within a given system. Valves generally come in two varieties: electro-magnetic and electric. Depending on their purpose, the features of the two types of valves differ. Therefore, it is important to understand the differences between the two types in order to make the appropriate selection.
The first difference between electro-magnetic and electric valves is in their operating principles. Electro-magnetic valves are operated by fluids that can be controlled by electromagnetic forces. Typically, these fluids are non-conductive, so the pressure or temperature has to be adjusted accordingly to ensure the electro-magnetic force can act on the valve. On the other hand, electric valves are operated by electricity, which can usually be adjusted accordingly to achieve its desired effect. This distinction is important in making the right valve selection.
The second difference between electro-magnetic and electric valves is their size and weight. Since electro-magnetic valves rely on fluids as its source of power, they are generally larger and heavier than electric valves. This means that selecting the right electro-magnetic valve for a particular system will require more precise measurements than selecting an electric valve since errors in size or weight may affect the performance of the system.
The third difference between electro-magnetic and electric valves is their response time. Electro-magnetic valves have a slower response time than electric valves, as they require a certain period of time before their desired effect is achieved. This is especially true for valves that require a precise change in pressure or temperature for their operation. As such, electro-magnetic valves often require more time to properly initiate and complete the desired action compared to electric valves.
The fourth difference between electro-magnetic and electric valves is their operating environment. Electro-magnetic valves are commonly used in environments with extreme temperatures, as they are more resistant to changes in temperature or pressure than electric valves. This increased resistance makes it ideal for applications in industries that require valves to handle extreme temperatures. On the other hand, electric valves are better suited for less extreme temperatures, as they are more sensitive to temperature changes.
Finally, the last and most important difference between electro-magnetic and electric valves is their affordability. Usually, electro-magnetic valves are more expensive than electric valves since they require a slightly more complex operation. This means that electric valves, being simpler to use, will also be more affordable. Therefore, when selecting a valve, consider not only its operating principles but also its cost.
In conclusion, electro-magnetic and electric valves are two distinct types of valves available in the market today. The differences between them can be significant when making the selection of a valve for a certain system. These differences can include the operating principles, size and weight, response time, operating environment and affordability. Therefore, it is important to understand the differences in order to make the appropriate selection for any given system.
