Solenoid valves are a bit unfamiliar to most people, but they are very useful for some industries in our daily lives. What are the characteristics of solenoid valves product? Today, we will talk about it.
1. It is very safe to use.
We know that internal and external leakage is an element that endangers safety. Other automatic control valves usually extend the valve stem, and the rotation or movement of the valve core is controlled by an electric, pneumatic, or hydraulic actuator. This must solve the problem of external leakage of the dynamic seal of the long-acting valve stem. But the automatic control solenoid valve is completed by using electromagnetic force to act on the iron core sealed in the magnetic isolation sleeve. There is no dynamic seal, so the external leakage is easy to block. The torque of the electric valve is not easy to control, and it is easy to produce internal leakage, or even pull off the head of the valve stem. And the solenoid valve structure is easy to control the internal leakage until it drops to zero. Therefore, the solenoid valve part is particularly safe to use, and it is especially suitable for corrosive, toxic or high and low temperature media.
2. It has small power and light appearance.
It is small in size which saves space, and it is light and beautiful. The solenoid valve response time can be as short as a few milliseconds, even the pilot solenoid valve can be controlled within tens of milliseconds, since it is a self-contained circuit, and it is more sensitive than other automatic control valves. 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 triggering the action, and it does not consume electricity at all.
3. The system is simple. And the price is low.
Solenoid valves system is simple that is easy to connect to the industrial computer and solenoid valves price is low, since the solenoid valve itself has a simple structure. It is easier to install and maintain than other types of actuators such as control valves. Since the solenoid valve is controlled by a switch signal, it is very convenient to connect with an industrial computer. In today's era, computers are popular and prices drop sharply, so the advantages of solenoid valves are even more obvious.
4. The applicable medium is limited since the adjustment accuracy is limited.
Solenoid valves usually have only on and off states. The spool can only be in two extreme positions and cannot be adjusted continuously. Though there are many new ideas trying to break through, they are still in the trial stage. So, the adjustment accuracy is still limited. At the same time, solenoid valves have high requirements for the cleanliness of the medium, and the granular medium cannot be used. If it is impurities, it must be filtered out first. In addition, viscous media cannot be applied, and the viscosity range of the media for specific products is relatively narrow.
