The largest AVK gate valve has been installed in a wastewater transportation project in Jiaxing City, China to fulfill the demands of growing wastewater production.
Pollution from wastewater continues to be a major challenge in the world. The shortage of water used in drinking, agriculture and construction is decreasing and proper methods of treating and recycling water is the key to sustaining our limited water resources.
Jiaxing City at Zhejiang Province in China encounter an increase in wastewater produced each day, and the existing treatment facility has been operating for a long time. As days goes by, this will result in critically increasing water transportation. Therefore, a sewage treatment expansion and discharge project were initiated for a 63.5km DN1400-DN2200 pipeline with a 400,000 m³/d maximum sewage transport capacity. Additionally, three midways lifting pump stations will be built.
In collaboration with AVK Shanghai, AVK Anhui provided 8pcs of DN1800 metal seated gate valves together with large diameter with large diameter DN2200 electric operated gate valve. The said valve weighs 27 tons and more than 7m height. It was installed at the pumping station's pipeline outlet which is connected to the wastewater treatment plant. It has a full-bore design with a lower head loss and pump consumption. A jacking screw, drain valve, by-pass valve and shoes-and-channel options guarantee the valve operates smoothly.
The valve is the largest gate valve produced by AVK Anhui in 2021. AVK Anhui was able to deliver the valve from scratch with the help of AVK Tech and our worldwide capabilities. Every stage reveals the excellence of our procedures - from designs to raw coatings, from machining to shot blasting, from coating to assembly, from testing to packing, and from delivery to final installation and commissioning.
Being one of the biggest production facilities in the AVK Group, AVK Anhui keeps refining and expanding their supply network to all local sales firms worldwide, particularly in large, specialized valves.
