Solenoid valve structure principle

       1, the external leakage is blocked, the internal leakage is easy to control, and the use is safe

Internal and external leakage is an element that endangers safety. Other automatic control valves usually extend the stem, and the rotation or movement of the spool is controlled by an electric, pneumatic, and hydraulic actuator. It is necessary to solve the external leakage problem of long-term action valve stem dynamic seal; Only the solenoid valve is the completion of the iron core sealed in the magnetic insulation tube of the electric control valve, and there is no dynamic seal, so the external leakage is easy to block. Electric valve torque control is not easy, easy to produce internal leakage, and even pull the stem head; The structure of the solenoid valve is easy to control the internal leakage until it is reduced to zero. Therefore, the solenoid valve is particularly safe to use, especially for corrosive, toxic or high and low temperature media.

       2, the system is simple, then the computer

The solenoid valve itself has a simple structure and low price, and is easier to install and maintain than other kinds of actuators such as regulating valves. What is more remarkable is that the automatic control system is much simpler and the price is much lower. Because the solenoid valve is a switch signal control, it is very convenient to connect with the industrial control computer. In today's era of computer popularity and sharply reduced prices, the advantages of solenoid valves are more obvious.

Cartridge valves provide equipment designers with many advantages in terms of conventional integrated valve blocks:

      1. System integrated valve block simplifies the machine pipeline.
Designing the valve block to meet the requirements of the equipment is better than designing the equipment to meet the requirements of the hydraulic system. Installation costs are usually significantly reduced

       2. Stop leaks.
External leakage is often the main reason for the limited application of hydraulic systems, and the O-ring fitted to the valve hole on the integrated valve block can eliminate external leakage.

     3. The downtime and maintenance time of the integrated loop valve block is greatly reduced, and the replacement of the component will not affect the related pipeline or it will not be solved
He parts.

    4. The integrated hydraulic circuit can be centralized on a single machine or dispersed for certain needs to optimize the pipeline.
In terms of installation, there are no specific installation requirements. Custom threaded insert integrated valve blocks offer unmatched flexibility
