Ensuring safe and reliable water supply - China

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. The Yuhuan and Wenling regions in particular suffer from the city's water shortage, which occurs every time there is a drought season. With 77 km of water supply pipeline and a total investment of 3.72 billion yuan in the water distribution pipe network, the Taizhou Water Diversion Project was subsequently launched by the city. It consists of a water intake project, a raw water transmission project, a water purification plant project, and project for a water supply pipeline. The project will greatly enhance the reliability of the water supply to the 3 million population of Taizhou.
 
AVK China was involved in this project since it needed an original and long-lasting solution. The project had a number of challenges, including a remote installation site, a harsh environment, a highly complexity of construction, and challenges with 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. The valves have a tilted disc shape for easier operation and a longer service life. 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. Additionally, the valve shaft seal can be changed while under pressure, making maintenance simple. 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.

Water supply distribution network project in India

Another project with focus on ensuring clean and safe drinking water is taking place in India. A water supply distribution network project is being worked on here by AVK China, and AVK Anhui has just finalised the first round of S756 DN3000 valve production.
Every year, AVK Anhui provides thousands of valves for projects. but with three metres from side to side, these enormous valves are the biggest supplied by the company to date.
The entire manufacturing process, including machining, shotblasting, coating, water pressure, and final assembly, has been supervised by AVK Anhui. The valves are now on their way to India where AVK India will be in charge of finalising the project. As with the case from China, these very big valves will be used to battle the challenge of water shortage, enhance the reliability of the water supply, and help ensure safe and clean drinking water.

WATER SUPPLY CASE STORIES

Hyderabad Metropolitan water supply and sewerage board

In 2019 Hyderabad metropolitan water supply sewerage board came up with a detailed project report in order to increase the water supply to Hyderabad. Reason being, Hyderabad one of fast growing IT hub in India- increase in migrating population forced the water authority to find a solution to cater the water supply needs for the new areas falling under HMWSSB limits.
