Solenoid Main Feature
Aug 30, 2017

(1) leakage plugging, leakage easy to control, the use of safety. Internal and external leakage is a factor that threatens safety. Other self-control valve is usually the stem out, by the electric, pneumatic, hydraulic actuator control spool rotation or movement. This is to solve the long-term action of the stem seal outside the leakage problem; only the solenoid valve is the role of electromagnetic force in the seal in the casing of the iron core to complete, there is no dynamic seal, so leakage easily blocked. Electric valve torque control is not easy, easy to produce internal leakage, and even pull off the stem head; solenoid valve structure type easy to control the internal leakage, until reduced to zero. Therefore, the use of solenoid valve is particularly safe, especially for corrosive, toxic or high and low temperature media.

(2) the system is simple, then access the computer, the price is low modest. Solenoid valve itself is simple structure, the price is low, compared to other types of actuators such as regulating valve easy to install and maintain. What is more significant is the composition of the automatic control system is much simpler, the price is much lower. As the solenoid valve is the switch signal control, and industrial computer connection is very convenient. In today's popular computer, the price dropped significantly in the era of the advantages of the solenoid valve is even more obvious.

(3) action express, power is small, lightweight appearance. Solenoid valve response time can be as short as several milliseconds, even the pilot solenoid valve can also be controlled in tens of milliseconds. Due to self-loop, than other self-control valve reaction more sensitive. Designed solenoid valve coil power consumption is very low, is energy-saving products; can also be done just trigger the action, automatically keep the valve position, usually not power consumption at all. Solenoid valve small size, both to save space, but also lightweight and beautiful.

(4) adjustment accuracy is limited, the applicable medium is limited. Solenoid valve is usually only two states of the switch, the spool can only be in two extreme positions, can not be continuously adjusted, (trying to break a lot of new ideas, but also in the trial trial stage) so the adjustment accuracy is subject to certain restrictions. Solenoid valve on the media cleanliness has a higher demand, with granular media can not be applied, if the impurities must first filter. In addition, viscous media can not be applied, and the specific product has a relatively narrow medium viscosity range.

(5) model variety, widely used. Although the inherent lack of solenoid valve, the advantages are still very prominent, so it is designed into a variety of products to meet a variety of different needs, the use of very wide. The progress of the solenoid valve technology is also around how to overcome the inherent deficiencies, how to better play the inherent advantages and start.
