There are many good brands of water balloon valves. I have listed ten well-known brands here for your reference. In fluid pipeline systems, valves are control components whose main functions are to isolate equipment and pipeline systems, regulate flow, prevent backflow, regulate and relieve pressure. 1 Langao Valve (founded in 1966, a national high-tech enterprise, a well-known trademark in China, a famous trademark in Gansu Province, a famous brand in Gansu Province, and one of the top ten valve brands) 2 Jiangyi (a national high-tech enterprise, a well-known trademark in China, and a famous brand in Zhejiang Province) Trademark, famous brand product in Zhejiang Province, one of the key enterprises in China's valve industry) 3 Aimeike (well-known trademark in China, one of the largest copper valve production and export bases in China, famous trademark in Zhejiang Province, Zhejiang famous brand) 4 Gongpai (created In 1946, Shanghai Famous Brand, Shanghai Famous Brand, an influential brand in the industry, a professional manufacturer of valves and valve electric devices) 5 Jingpai (a famous trademark in Beijing, a key state-owned enterprise manufacturing high and medium pressure valves and steam traps, Top 500 Chinese Machinery Enterprises) 6 Dagao (founded in 1956, a well-known trademark in China, a national high-tech enterprise, and a supporting unit for the localization of key valves for national key equipment) 7 Feiqiu (founded in 1958, the largest valve manufacturer in China One of the manufacturing enterprises, a high-tech enterprise, a famous trademark in Sichuan Province, and a famous brand in Sichuan) 8 Shangva SF (the vice-chairman unit of the Valve Branch of China General Machinery Association, one of the key enterprises in the national valve industry, and one of the top ten valve brands in China) 9 Lipai (a well-known trademark in China, a famous trademark in Tianjin, exempt from export inspection, a group company integrating scientific research, production, sales, storage and transportation, and import and export operations) 10 Open valve (founded in 1959, a high-tech enterprise, a famous trademark in Henan Province, Vice Chairman Unit of China General Machinery Association, a large key enterprise) I don’t know if you have noticed that these valves are all old brands and the factories were established relatively early. If there are any good brands to recommend, I would recommend the brand Amico. I remember that the water valve in my old house was from this brand. You may not believe it when I tell you. It has been in use for more than ten years and has not been replaced. I highly recommend it.
