The implementation of automated instrument Pioneer solenoid valve with its many advantages more and more favored by the market, demand jumped year by year. Now we want to understand the advantages and disadvantages of the solenoid valve to do one by one.

First, the main advantages of electromagnetic valve introduced

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 has to solve the long-term action stem stem seal leakage problems.

A. Internal leakage

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.

B. Leakage

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 is easy to block.

In summary, the use of solenoid valve is particularly safe, especially for corrosive, toxic or high and low temperature media.

Second, the solenoid valve shortcomings

1) adjustment accuracy is limited

Solenoid valve is usually only two states of the switch, the spool can only be in two extreme positions, can not be 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.

2) flow media

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.

There are advantages will be shortcomings, but some of these shortcomings can be avoided by selection.
