AVK China are involved in two major water supply projects and has supplied various DN2400 and DN3000 butterfly valves.
More and more cities are facing water shortage and a serious challenge of providing adequate freshwater to their residents. With increasing populations and long periods of drought, they are forced to innovate new ways to ensure safe and clean water supply.
Taizhou Water Diversion Project
This is also the case in the city of Taizhou, China. Here, the city is experiencing water shortage and every drought season, the lack of water has a negative impact on especially the Yuhuan and Wenling areas. Therefore, the city started the Taizhou Water Diversion Project, which includes a water intake project, a raw water transmission project, a water purification plant project, 77 km of water supply pipeline and a total investment of 3.72 billion yuan in the water distribution pipe network. The project will greatly enhance the reliability of the water supply to the 3 million population of Taizhou.
As this project required an innovative and sustainable solution, AVK China was involved. The project presented various difficulties such as a remote installation site, a harsh environment, high complexity of construction and difficulties in product maintenance. In response to this, high efficiency, durability, and low maintenance costs were the core considerations for the selection of the right valves. AVK China provided 36 large-diameter double eccentric butterfly valves of DN2400, which meet the highest quality standards, can withstand the harshest conditions, and ensure that the products comply with drinking water certification.
The AVK double eccentric butterfly valves have several features, which all contribute to the high quality of the final solution to the customer. First, the valves have a tilted disc design for extended service life and ease of operation. Second, AVK is a leader in rubber composite and coating technologies, both of which are critical to our products and their life span and durability.
This also means that the valve disc sealing ring is processed by AVK’s unique EPDM rubber, which is certified for drinking water and has excellent resilience performance. In addition, the valve shaft seal can be replaced under pressure, which is easy to maintain. This ensures safe sealing from the inside to the outside, and effectively prevents impurities from entering. Finally, the inner and outer epoxy coatings of the valve are sprayed according to the highest standards - DIN30677-2 and GSK.
