Over the past twenty years, Mengzhou Valve has grown from scratch, from small to strong, inseparable from the attention and care of party and government organs at all levels and colleagues from all walks of life, the support and love of new and old customers, and the joint efforts of all employees. I sincerely express my gratitude here.

Over twenty years of ups and downs have shaped a unique corporate culture in Mengzhou. We not only achieve a win-win situation with customers on the path of building a brand, but also provide a good career development stage for every outstanding employee. Generations of people from Mengzhou have bravely shouldered the mission of "advancing development, carrying wealth with virtue, technological innovation, and serving the country through industry", closely surrounding the core leadership of the company.

Quality oriented, achieving a win-win situation.

Quality - Achieve a brand, create a good brand, and establish a solid foundation.

Mengzhou - Professional Choice! Looking back on the past, the company has always adhered to the development concept of "technology leading the future", customer-centered, market-oriented, and achieved fruitful results in product innovation and technological research and development, paving a path of innovation in the history of enterprise development.

We will continue to work together in the same boat and forge ahead hand in hand. We sincerely hope that in the future, with everyone's love and companionship, we will unite more closely to strive for a win-win situation for the enterprise, customers, employees, and society, and to create a brilliant tomorrow for Mengzhou!
