The main features of the miniature solenoid valve

The main features of the miniature solenoid valve:
1, leaks blocked, easy to control leakage, use safety
Internal and external leaks are elements that endanger safety. Other self-controlled valves usually extend the valve stem and the spool, which is controlled by the electric, pneumatic and hydraulic actuators, can rotate or move. This must solve the problem of external leakage of the valve stem dynamic seal during long-term operation; only the solenoid valve is operated by the electromagnetic force acting on the core sealed in the magnetic isolation sleeve of the electric control valve. There is no dynamic seal, so the leakage is easy to block. . Electric valve torque control is not easy, easy to produce internal leakage, and even break the stem head; micro-magnetic valve structure type easy to control the internal leakage until it is reduced to zero. Therefore, the solenoid valve is particularly safe to use, especially for corrosive, toxic or high-low temperature media.
2, the system is simple, then the computer, low price
The miniature solenoid valve itself has a simple structure and a low price, and is easier to install and maintain than other types of actuators such as regulating valves. What is even more remarkable is that the self-contained system is much simpler and the price is much lower. Because the solenoid valve is a switch signal control, it is very convenient to connect with the industrial control computer. In today's era of widespread computer availability and sharply lower prices, the advantages of solenoid valves are even more pronounced.
3, action express, small power, light and compact
Micro solenoid valve response time can be as short as a few milliseconds, and even pilot solenoid valves can be controlled within tens of milliseconds. Because of self-looping, it reacts more sensitively than other self-controlled valves. Well-designed solenoid valve coil power consumption is very low, is an energy-saving product; can also be achieved simply trigger action, automatically maintain the valve position, usually no power at a time. The electromagnetic valve has a small size, which saves space and is light and beautiful.
4, limited adjustment accuracy, limited media
Micro-electromagnetic valve usually only two kinds of switch state, the valve can only be in two extreme positions, can not be continuously adjusted, (a lot of new ideas trying to break through, but still in the experimental trial phase) so the adjustment accuracy is also subject to certain restrictions.
Miniature solenoid valves have higher requirements on the cleanliness of the medium. The granular media cannot be used. If impurities are contained, they must be filtered first. In addition, viscous media cannot be used, and the specific product is suitable for a relatively narrow range of media viscosity.
5, a variety of models, a wide range of uses
Although the miniature solenoid valve is inherently inadequate, the advantages are still very prominent, so it is designed into a wide variety of products to meet a variety of different needs and uses are extremely wide. The advancement of micro-electromagnetic valve technology is also centered on how to overcome congenital deficiencies.
