Main features: 1. The self operated regulating valve does not need additional energy, and can work in the situation without electricity and gas, which is convenient and energy saving. 2. The pressure sections are narrow and cross each other, with high adjustment accuracy. 3. The pressure setting value can be set continuously during operation. 4. For the pressure adjustment behind the valve, the ratio between the pressure in front of the valve and the pressure behind the valve is 10:1~10:85. With the rubber diaphragm detection, the actuator has high detection accuracy and sensitive action. 6. The pressure balance mechanism is adopted to make the regulating valve responsive and controllable.

China encourages and devotes itself to the research and development of high-end electric valves. The innovation of electric valve industry and the improvement of technical competitiveness have become increasingly important. As an automatic equipment to control fluid, valves are widely used in industry. It can be said that every industry can not do without electric butterfly valves. Valves have been involved in many aspects of the national economy. It can be said that electric on-off butterfly valves are important basic equipment of our national economy. After 60 years of development since the founding of the People's Republic of China, China's valve industry has formed more than 70 categories of valve systems in ten major categories.
