After years of efforts, Sunway Technology has made breakthroughs in the core technologies of many products: 1) Proportional electromagnet 2) Displacement sensor 3) Proportional control amplifier 4) Pressure compensator 5)Spool valve body coupling parts, etc., we have developed piece proportional valves and servo proportional valves, accumulated our own technical advantages, and are in the leading position in the same industry. Based on the early stage of Shanghai Sunway, Sunway Technology has a clear direction of development. In the past 20 years, it has been committed to replacing stuck neck solutions in the high-end hydraulic field. In the future, it hopes to provide overall hydraulic system solutions like Sany replaced Carter and Huawei replaced Cisco, and become a precision machinery and electrical engineering company, with a place in the high-end market.
