An electrical proportional valve is a pressure and flow output component that is proportional to the input voltage signal of the proportional electromagnet inside the valve, causing displacement of the working valve core and changes in the size of the valve port. The displacement of the valve core can also be feedback in mechanical, hydraulic, or electrical forms. Electrohydraulic proportional valves have various advantages, such as diverse forms, easy composition and use of electrical and computer control of various electro-hydraulic systems, high control accuracy, flexible installation and use, and strong anti pollution ability. Their application fields are increasingly expanding. The selection and inclusion of electrical proportional valves for quick and easy automation, as well as the development and production of plug-in proportional valves and proportional multi way valves, fully consider the characteristics of engineering machinery use and have functions such as pilot control, load sensing, and pressure compensation. Its emergence is of great significance for improving the overall technical level of mobile hydraulic machinery. Especially in the fields of electronic control pilot operation, wireless remote control, and wired remote control, it has shown good application prospects.

Born Optics Co., Ltd. was established in 1986 as a Hong Kong funded private enterprise. Formerly Fuji Optics Co., Ltd. and Bern Optics Co., Ltd., until 2010, in order to achieve higher management and production efficiency, they were officially integrated into Bern Optics Co., Ltd. So far, the factory area of the industrial park has reached 850000 square meters. The combination of technology and production capacity has made Bern the current global glass panel manufacturer, with a global market share of over 60%. The annual total output value of the two major production bases in Shenzhen and Huizhou is as high as 30 billion yuan.
