DAUME(Shanghai) Control Technology Co., Ltd.

D + R specializes in the production of valves and high quality electric actuators and is headquartered in Shanghai. As a pioneer in electric actuators and a pioneer in new technologies, its advanced DC brushless electric actuator technology has become the de facto industry leader.

D+R series electric actuator has a significant progress in technical aspects, such as energy saving, speed control, flexible switch, high-precision control, safety and reliability, etc.; The applicable conditions are harsher and applicable scope expands unceasingly. In product R&D, manufacture, sales, global services and other links, D+R is strctly in compliance with ISO9001 and TUV standards, to ensure providing users with satisf D+R products are widely applied in following fields: Power station, Oil exploitation, Oil and gas pipeline, Chemical plant, Refining, Steel mill, Cement plant, Wastewater Treatment Plant, Pharmaceutical factory, Boiler factory etc.,

D+R engineers have more than 40 years' R&D, design and manufacturing experience of electric actuator. D+R people have been trying to develop a new generation of DC brushless variable-speed actuator to replace conventional AC type, a dual power supply actuator to replace conventional pneumatic type.

In 2000, D+R collaborated with the Industrial university in DC brushless motor control technology, and succeeded in research and practical application of DC control technology. This new technology product application is a revolution in the electric actuator industry, proving that our technology is advanced;

Core products: Electric/ Pneumatic actuator, Electro-hydraulic actuator, Handwheel gearbox, and different kinds of valves etc.

Factory address: Science and technology park, ZhongYuan institute of technology, longhu town, ZhengZhou city, henan province.

History of Enterprise

In 1976, D+R began the research and production of electric actuator, which was jjust a small company with 11 staff.

In 1988, D+R launched products with functions of digital display and panel button commissioning.

In 1995, Infrared explosion-proof electirc actuators were applied in a Russian oil refinery.

In 2000, D+R began to research the application of BLDC motor in electric actuators and And put into production.

In 2003, D+R sold the brushless DC varicble-speed electric actuator for the first time And applied to China's first long distance, large diameter, high pressure coal slurry pipeline transportation.

In 2007, Based on the permanent magnet DC brushless speed control electric actuator, we have developed a dualpower/reset type electric actuator.

Providing you with the best quality electric actuators is the task of D+R engineers!
