Guangdong Yuedian Jinghai Power Generation Co., Ltd. is located on the east bank of Jinghai Bay in Huilai County, Jieyang City, Guangdong Province. In 2018, a 660MW unit of Zhuhai Jinghai Power Generation Co., Ltd. completely replaced 34 ABB locators with its air damper, and has been operating without any faults for 4 years. In 2019, another 660MW unit was retrofitted to replace ABB and successfully delivered for use. It has been operating for 3 years without any faults. At the beginning of 2020, replaced the German SIEMENS positioner on the turbine side of a 1000MW unit to control the American Fisher valve. This is a zero scanning project for domestic locators to replace imported products in key equipment of large units

Liugang coking riser control system, consisting of 55 units on this production line, is equipped with Tuoyou brand intelligent valve positioners. After three months of trial operation in harsh outdoor environments with high temperatures and large dust, it passed the acceptance inspection and was successfully put into operation. There are still 10 production lines like this, and Tuoyou people will continue to work hard to strengthen quality, provide excellent services, replace domestic products, and become an industrial powerhouse!

Anshan Qicai Chemical Co., Ltd. is a subsidiary registered by Anshan Huifeng Group. Huifeng Group is currently a pilot and industrialization base of the National Dye Engineering Research Center, a national postdoctoral research workstation, and has established the Liaoning Province Anshan Huifeng Chemical Engineering Technology Research Center (Coal Tar Fine Chemicals and Organic Pigments Engineering Technology Research Center). We purchased a batch of Tuoyou explosion-proof intelligent valve positioners in 2019 and have been using them for 3 years. During this period, the control effect has been good and zero failures have been achieved.
