A proud legacy of excellence that stretches back to 1977, The history of our company is a testament to resilience and vision, marked by three transformative phases of growth: Phase 1 (1976-1990), Phase 2 (1992-2002), and Phase 3 (2002-2023). Our journey began in 1976, when the visionary founder Chen Jianqing and his committed associates boldly ventured into the creation of high-quality valves. Despite the odds, they delivered their inaugural batch of valves under constrained processing conditions, securing the company's foundational capital. By 1977, driven by relentless excellence, they collaborated with Longwan school office to establish the innovative Wenzhou Tianlong Petrochemical Machinery Factory, specializing in sealing rings. The early years presented challenges like a basic product structure and limited technical prowess, but the founders' ingenuity and determination overcame production and sales hurdles impressively.
In 1979, fueled by expansion aspirations, the company broadened its product range to include air valves, packing parts, pistons, piston rods, connecting rods, and bearing bushings. By 1984, the enterprise embraced the private sector, rebranding as Wenzhou Air Compressor Valve Factory and proudly becoming Wenzhou's pioneering specialist in compressor components.
By 1990, our products achieved market acclaim, enabling us to ascend into the ranks of designated production enterprises under the Petrochemical Industry Bureau (formerly the Ministry of Chemical Industry). We became esteemed members of the refining and chemical spare parts network of China National Gas Corporation, joining the prestigious spare parts resource market of China Petrochemical.
In 1992, a strategic shareholding reform heralded our rebranding as Wenzhou Jianqing Industrial Company, marking a pivotal evolution in our organizational journey and setting the stage for future growth.
With the dawn of the new millennium, we embraced a culture of continuous innovation, shifting from import emulation to autonomous design and R&D. Through incremental yet substantial advancements, we have fortified our standing, emerging as industry frontrunners.
Product category introduction: Jianqing Industrial's core product offerings encompass three principal wear-resistant components: air valves, piston ring support rings, and packing rings. We also provide gas regulators (actuators) and check valves. Our design philosophy has evolved significantly, especially evident in our air valves, advancing from initial metal mesh designs to an array of structural types such as ring inclined, mushroom, and infinity valves.
Our expansive client base proudly spans across numerous Chinese provinces, showcasing our vast reach and trusted reputation. bd489cc6
