The specified cracking pressure is required to open the valve to allow free flow direction.
The main features of YUKEN solenoid valve are plugged outside the solenoid valve, the internal leakage is easy to control, and the use is safe. Internal and external leakage is an element of safety compromise. Other self-controlling valves usually extend the stem and the movement of the spool is controlled by an electric, pneumatic, and hydraulic actuator. This must solve the problem of external leakage of the long-term action stem dynamic seal; only the solenoid valve is completed by using electromagnetic force to act on the iron core sealed in the magnetic isolation sleeve of the electric control valve, and there is no dynamic seal, so the external leakage is easy to block. The torque control of the electric valve is not easy, it is easy to produce internal leakage, and even pull off the head of the valve stem; the structural type of the solenoid valve is easy to control the internal leakage until it drops to zero. Therefore, solenoid valves are particularly safe to use, especially for corrosive, toxic or high and low temperature media.
The YUKEN solenoid valve system is simple, easy to connect to the computer, and inexpensive. The solenoid valve itself has a simple structure and low price, which is easier to install and maintain than other types of actuators such as control valves. More notably, the composed automatic control system is much simpler and much less expensive. Since the solenoid valve is controlled by a switching signal, it is very convenient to connect with the industrial control computer. In today's era of computer popularization and sharp price decline, the advantages of solenoid valves are even more obvious. SMC solenoid valve action express, small power, lightweight shape. The response time of the solenoid valve can be as short as a few milliseconds, and even the pilot-operated solenoid valve can be controlled within tens of milliseconds. Due to the self-contained circuit, it is more responsive than other automatic control valves. Properly designed solenoid valve coil power consumption is very low, is an energy-saving product, but also can be only triggered action, automatically maintain the valve position, usually do not consume electricity at all. The small size of the solenoid valve is both space-saving and lightweight. The adjustment accuracy of the solenoid valve is limited, and the applicable medium is limited. Solenoid valves usually only have two states of switching, the valve spool can only be in two limit positions, can not be continuously adjusted, (try to break through the new ideas are many, but are still in the experimental trial stage) so the adjustment accuracy is still limited. YUKEN solenoid valve has high requirements for the cleanliness of the medium, and the media containing particles cannot be applied, and if it is an impurity, it must be filtered out first. In addition, viscous media can not be applied, and the specific product is suitable for a relatively narrow range of media viscosity. YUKEN solenoid valves are available in a wide range of models and uses. Although the solenoid valve has inherent deficiencies, the advantages are still very prominent, so it is designed into a variety of products to meet a variety of different needs, and the use is extremely extensive. The progress of solenoid valve technology is also centered on how to overcome innate deficiencies and how to better play the inherent advantages;
