Recently, Bensv, together with Hefei General Environmental Control Technology Co., Ltd., Changsha University of science and technology and Hefei General Machinery Research Institute Co., Ltd., won the second prize of China machinery industry science and Technology Award for the project of "high parameter air valve test technology and product application for large water conveyance project".

This award-winning project overcomes the difficulty of measuring and accurately calculating the performance parameters of air valves for large-scale water conveyance projects, which is conducive to the development of high parameter air valves and the selection of users. Air valve is an important valve in water conveyance project, which is very important for the safe and energy-saving operation of water conveyance project. This award-winning achievement has improved the overall research and development level of air valve in China, and the key technology has reached the international high level. The performance test of large-scale air valve has been realized. The air valve can be parameterized, which is convenient for the selection of users. It reduces the probability of pipe burst of water delivery project, improves the water delivery efficiency of water delivery project, and makes contributions to environmental protection, energy conservation and effective utilization of resources.
