Japanese SMC solenoid valve

Main features of SMC solenoid valve

1. The main features of SMC solenoid valve are that the solenoid valve blocks external leakage, internal leakage is easy to control, and it is safe to use. Internal and external leakage is a safety hazard. Other automatic control valves usually extend the valve stem and are operated by electric, pneumatic, hydraulic actuators< /U>Control the rotation or movement of the valve core. This must solve the problem of external leakage of the dynamic seal of the valve stem during long-term operation;only the solenoid valve uses electromagnetic force to act on the iron core sealed in the magnetic isolation sleeve of the electric regulating valve. There is no dynamic seal, so the external leakage is easy to be blocked. .

　2. It is difficult to control the torque of the electric valve, and it is easy to cause internal leakage, and even break the valve stem head;the structure of the solenoid valve makes it easy to control the internal leakage until it drops to zero. Therefore, solenoid valves are particularly safe to use and are especially suitable for corrosive, toxic or high and low temperature media.

3. The SMC solenoid valve system is simple, easy to connect to a computer, and the price is low. The solenoid valve itself has a simple structure and low price. It is easier to install and maintain than other types of actuators such as control valves. What is more significant is that the automatic control system is much simpler and the price is much lower.

　4. Since the solenoid valve is controlled by a switch signal, it is very convenient to connect to the industrial control computer. In today's era when computers are popularized and prices have dropped significantly, the advantages of solenoid valves are even more obvious. SMC solenoid valve has fast action, small power and lightweight appearance.

The response time of the solenoid valve can be as short as a few milliseconds. Even the pilot solenoid valve can be controlled within a few milliseconds. Within ten milliseconds. Due to its self-contained loop, it is more responsive than other automatic control valves.

5. A properly designed solenoid valve coil has very low power consumption and is an energy-saving product;it can also automatically maintain the valve position by simply triggering the action, and does not consume any power at all. The solenoid valve has a small appearance and size, which not only saves space, but also is light and beautiful. The solenoid valve has limited adjustment accuracy and limited applicable media.

6. Solenoid valves usually only have two states: switch and switch. The valve core can only be in two extreme positions and cannot be continuously adjusted. (There are many new ideas trying to break through, but they are still in trials. stage) so the adjustment accuracy is still subject to certain limitations.

7. SMC solenoid valves have high requirements for media cleanliness. Media containing granular particles cannot be used. If they are impurities, they must be filtered out first. In addition, viscous media cannot be used, and the viscosity range of media suitable for specific products is relatively narrow.

8. SMC solenoid valves have various models and are widely used. Although solenoid valves have inherent shortcomings, their advantages are still very prominent, so they are designed into a variety of products to meet various needs and are extremely versatile. The progress of solenoid valve technology also revolves around how to overcome inherent shortcomings and how to better utilize inherent advantages.
