Our stable product quality and efficient cost control have won the trust of global markets such as Europe, America, Japan, and South Korea.
I. Brand Origin:
In 1984, the company's predecessor, "Wafangdian Santang Foundry, " was officially established on Changxing Island, Dalian, marking the beginning of its exploration in the field of metal casting.
In 1990, the company moved to Santang Village and was renamed "Wafangdian Seagull Valve Factory, " focusing on the production of core valve components, laying a professional manufacturing foundation.
In 1991, the company pioneered export business, cooperating with trading companies to export butterfly valve bodies to Asian markets such as South Korea and Japan.
In 1996, a new modern factory was built and named "Dalian Xingfeng Valve Co., Ltd. "
In 1998, the company successfully expanded into the European and American markets, achieving a leap from Asian to global markets.
In 2005, "Dalian Ruichi Industrial Co., Ltd. " was officially established, focusing entirely on export business, and its professional and international operating system has become increasingly mature.
In 2010, to expand production capacity and optimize layout, the factory was relocated to Xietun Town, and "Wafangdian Wudao Baoyang Machinery Factory" was established, forming a dual-factory collaborative production model.
In 2012, the company invested heavily in introducing precision equipment such as CNC lathes, high-precision machining centers, and coordinate measuring machines, realizing the digital and intelligent upgrading of the production process. Currently, the company has built a complete production system covering casting, forging, stamping, and machining.
