The birth of the valve has a long history, the earliest can be traced back to the Spring and Autumn Period, after the 18th century to the 19th century, with the development of European smelting technology and hydraulic machinery, especially the steam engine in mining, smelting, textile, machinery manufacturing and other industries quickly spread, the requirements for the valve gradually increased.In the 1990s, China's valve manufacturing industry began to develop rapidly after the introduction and digestion of foreign advanced technology, filling in some special industrial control gaps.

Due to the uneven technology and the immature environment, the domestic valve manufacturing industry shows a state of urgent need for development in the early stage, with a very broad space for growth.No matter in the core technology, professional personnel, or in the production equipment, production line, domestic valve enterprises generally have obvious shortcomings, insufficient advantages.At this time, Zhejiang Wenzhou Yongjia County state valve Co., LTD. Arises at the historic moment.National engineering inherits the spirit of Chinese craftsmen and promotes and revitalizes national enterprises.

Since its establishment, Guogong has been aiming to become a model of the industry, relying on the continuous improvement of R & D technology and the increasingly perfect production chain, it has made great progress all the way and written down the glorious development history. In 1999, Yongjia Guogong Valve Co., Ltd. was established, initially opening up the economic market; in 2003, Dongfang foundry was established to realize independent casting, production and sales; in 2011, Zhejiang Guogong Valve Co., Ltd. was established to create its own brand; in 2012, it was renamed as Guogong Valve Co., Ltd. with no regional enterprise logo; in 2013, it was renamed as Guogong Valve Co., Ltd With an annual investment of 200 million yuan, Guogong Holding Group Co., Ltd., headquartered in Lishui, Zhejiang Province, was established; Nanping Guogong Machinery Casting Co., Ltd. was established in October 2019 to further expand the casting scale.

In the process of steady development, the achievements made by Guogong holding group are obvious to all. Its technical strength and production scale have been certified by many authorities. In 2012, it obtained iso9001:2015 quality management system certification, iso14001:2015 environmental management system certification, and iso45001:2018 occupational health and safety management system certification; in 2013, it obtained TS certification of special equipment manufacturing license of the people's Republic of China; in 2017, the company established a research and development department, developed more than 20 patents, and obtained the special equipment manufacturing license of the people's Republic of China in 2018 In the same year, it obtained the CE certification of European communist system; in 2019, it obtained the Xinhua water saving certification and API-6D certification of American Petroleum Association; in March 2020, it obtained the three system certification issued by China Quality Certification Center.

Guogong has always been standing in the perspective of customer demand, with advanced technology and production led development, deeply ploughed the industry for more than 20 years, providing continuous power for the domestic valve manufacturing industry. In the future, we will continue to strengthen our faith, ride the wind and waves, and make the strongest voice of China's valve industry!
