Chongqing Yuhui Keyu Machine Electricity Equipment Corp. Ltd. is engaged in the research and development of new style float valves and other air cooling equipment. Along with the wide application of high-tech products, we are using innovative technology, and have developed a new type of plastic level control valve (floating ball valve) with the theory of self-locking differential pressure. It has good features such as long lifetime, less abrasion, corrosion-resistance, non-pollution, quicker water flow rate and very low prices which significantly reduce customers' cost accordingly. Moreover, the performance of the existing copper valves and stainless steel valves are difficult to match our products' advantages. The new product sells well around the world, being installed in cooling towers, evaporative coolers, water storage products, and other environmental treatment areas, especially high and low water tanks, cooling towers of water level controlling, and universal regulatory functional products. It is suitable for installing in all kinds of different angles in water tanks. At present, it's gradually getting popular and widely installed in Guangdong, Shanghai, Shandong, Zhejiang and other places in China relying on a number of distributing agencies. To underline the idea of protecting patent intellectual property, our company has applied for a number of patents. Furthermore, the product has now been utilized by the Quality and Technical Supervision of Chongqing "Sealing Performance" and "Body Strength" excellent grade test.
