Botou Valve Manufacturing Industry Co., Ltd.

It is expected that on March 19, 2009, with the sound of firecrackers, Botou Valve Manufacturing Industry Co., Ltd., which is located in the mechanics workshop of the Botou Fertilizer Plant, was established. Mr. Liu Wanguo, who has worked hard for more than ten years, finally has his own company. Although he is renting a factory building, his dream is set sail from now on (the registered trademark "Hangtong" is based on Mr. Liu who worked in the Second Academy of the Ministry of Aerospace Industry. To reach the five continents, marketing the good goals of the world).

With the good development of the enterprise, some major brand valve companies have established strategic partnerships with our company. "Li" Dazhan Valve has been cooperating since 2005. Cooperated with Chuanxiao Valve to produce flow meters for the construction of Beijing Olympic venues. The production of DN500 and DN600 filters are used in China, Hong Kong Water Supply Project and Tianjin Yuanda Valve Co., Ltd. To produce soft-seal gate valves for export to Russia and Vietnam. The long-held ideal of "Hangtong" to go abroad finally came out on November 17, 2007. In 2009, DN500 and DN600 soft-sealed gate valves were successively developed. Due to castings, they have been in the production of large-diameter valves. They were used in June 2009. Our 315KWA transformer has established its own casting workshop and became the first manufacturer in the valve industry to use electric furnaces and full resin sand to produce valve castings. The appearance, materials, and structural dimensions have been comprehensively improved. As a result, the product became an instant success and quickly opened up the international market.

In 2013, we purchased 20 acres of land at the north end of No. 2 Road as a new plant, and purchased a 2.6-meter vertical lathe to provide guarantee for the production of size-caliber valves. DN800 soft-sealed gate valve was successfully trial-produced in 2012, DN700/DN1000 soft-sealed gate valve was successfully trial-produced in 2013, DN900 soft-sealed gate valve was successfully trial-produced in 2014, and DN1200 soft-sealed gate valve was also successfully tested in 2015. And in September 2018, 14 sets of German standard F5 with bypass DN1200 valves produced for the German company were successfully shipped. It provides valuable experience for our company to produce large-caliber valves in the future, from casting to machining, spraying, assembly, and pressure testing. From the first one per day to the last three per day, when we reproduce large-diameter valves, from production, The quality will be completed with confidence in the particle size until the delivery period.

In July 2016, it passed the 9001 quality management system certification of TÜ V Rheinland, and gradually developed to the European customers of CMEC. The high product quality has guaranteed our company′s production. In October 2018, it was passed the on-site audit of the quality management of Hebei Province′s quality product enterprises. After 2016, the environmental protection storm has swept across all processing industries, especially the valve industry with castings accounting for more than 90%, which has the greatest impact, but there is no other method, only a positive face. Our company actively adjusted and arranged production line production, and other provinces and cities produced production to actively respond. On January 19, 2017, the spraying assembly line obtained the pollution discharge permit, and actively dispatched during the staggered production period to ensure the smooth completion of the order.
