1, external leakage plugging, internal leakage is easy to control, the use of safety Internal and external leaks are factors that endanger security.
Other control valves usually extend the stem, which controls the rotation or movement of the spool by electric, pneumatic and hydraulic actuators.
2, the system is simple, then pick up the computer, low price
The solenoid valve itself is simple in structure and low in price, which is easy to install and maintain compared with other kinds of actuator such as regulating valve.
3, the Action Express, the power is small, the shape is lightweight
Solenoid valve response time can be as short as several milliseconds, even the pilot solenoid valve can be controlled within dozens of milliseconds.
4, adjust the precision is limited, the application medium is limited
Solenoid valve usually only two types of state, the spool can only be in two limit positions, can not be continuously adjusted, so the adjustment accuracy is also subject to a certain limit.
5, a variety of models, wide range of uses Although the solenoid valve is congenitally deficient, the advantages are still very prominent, so the design of a variety of products to meet a variety of different needs, the use of a very wide range.
