Abstract

The working principle of electro-hydraulic proportional valve is that the proportional electromagnet in the valve starts to work under the drive of voltage signal, the displacement of the working valve spool and the change of the size of the valve port are implemented. On this premise, the input of voltage proportional pressure is carried out, and then the corresponding output of the flow is carried out. The displacement feedback of the spool can also be achieved in the form of electrical, mechanical or pressure. The reason why electro-hydraulic proportional valve continues to expand the application field lies in its own unique advantages, such as variety of types, convenience in setting up different electro-hydraulic systems, anti-pollution ability, ultra-high control accuracy and flexibility of setting up applications. Besides, with the advent of new products and the overall promotion of technology in mobile hydraulic machinery, new products including plug-in valve and proportional multi-way valve, are characterized with pilot control, load sensing and pressure compensation and other functions.
