Main features
（1）Leakage blocking extinction, internal leakage is easy to control, safe to use. Internal and external leaks are elements endangering the security. Other automatic control valve will usually protrude stem, by the electric, pneumatic and hydraulic actuators to control the core rotating or moving. This is all a long-term action to resolve the external dynamic seal valve stem leakage problems; only solenoid valve uses electromagnetic acting on core that sealed in compartment sleeve to complete, there is no dynamic sealing, so it iseasy to block leakage. Electric valve torque control is not easy, prone to internal leakage, and even pulled off the stem head; solenoid valve structural type easily controls the internal leakage, until reduced to zero. Therefore, the use of solenoid valve is specially safe, and especially suitable for corrosive, toxic or high temperature media.
（2）System is simple, easy to connect to computers, with low price. Solenoid valve itself structure is simple, the price is also low, compared to regulating valve and other types actuators, it is easy to install and maintain. More significant is the automatic control system consisting much simpler, the price is much lower. As the solenoid valve is controlled by a switching signal, and is easy to connect with industrial control computer. In today's widespread use of computers, an era of declining prices, the solenoid valve has even more obvious advantages.
（3）Action Express, power tiny, lightweight shape. Solenoid valve response time can be as short as a few milliseconds, even in the pilot-type solenoid valve can control within tens of milliseconds. Since the two into a loop, it is more responsive to other automatic control valve. Properly designed sloenoid valve coil power consumption is very low, is energy-saving products; can be triggered simply moves automatically to maintain valve position, usually not at power consumption. Solenoid valve shape size is small, not only save space, but also light and beautiful.
（4）Regulative accuracy is limited, applicable medium is limited. Solenoid valves are usually only open and close two states, core is only in two limited positions and can not be continuously adjustable, (trying to break a lot of new ideas, but are in the pilot trial phase), so regulative accuracy is also subject to certain restrictions.
Solenoid valve has higher cleanliness requirements to media, including granular media can not be applied, it belongs to impurities, it should be filtered. In addition, the viscous medium can not be applied, and the applicable medium viscosity range of specific product is relatively narrow.
（5）Models varied and widely used. Although the solenoid valve congenitally deficient, advantages are still very prominent, so we designed a wide range of products that meet a variety of different needs, uses are very extensive. Solenoid valve technology advances are also revolved around how to overcome the inherent deficiencies, how to give better play to the inherent advantages initiated.
