Product Description
Check valves are indispensable for safeguarding equipment from potential damage and mitigating safety hazards associated with reverse flow. The market is brimming with a myriad of check valve types from various manufacturers. For our discerning clientele, their engineering teams often face the intricate task of selecting solutions that are both technologically advanced and economically viable for their unique applications.
Established in the industrious year of 1977, Wenzhou Jianqing Industrial Company's storied journey is gracefully segmented into three dynamic phases. Phase 1 spans from 1976 to 1990, Phase 2 from 1992 to 2002, and Phase 3 from 2002 to 2023. The visionary founder, Chen Jianqing, alongside a dedicated team, embarked on this journey in 1976, crafting valves under challenging conditions. Their relentless determination bore fruit with the delivery of the inaugural valve batch, securing their first vital capital. By 1977, their industrious spirit led to the establishment of Wenzhou Tianlong Petrochemical Machinery Factory, in alliance with Longwan School Office. Initially, the venture focused on crafting seal rings amidst complex production challenges. Yet, the founders faced obstacles head-on, methodically resolving production and sales quandaries to lay a solid foundation for future growth.
By 1979, driven by an insatiable quest for progress, the company embarked on a strategic expansion of product categories. Transitioning from the singular focus on sealing parts, they diversified into air valves, packing elements, pistons, piston rods, and bearing bushings. By 1984, the school transferred to private ownership, transforming into Wenzhou Air Compressor Valve Factory, establishing a pioneering presence as Wenzhou's first comprehensive compressor parts manufacturer.
Fast forward to 1990, when the market began to acknowledge the superior quality of their products. This recognition enabled entry into the esteemed circle of designated production enterprises for the Petrochemical Industry Bureau (the former Ministry of Chemical Industry). They also became a crucial member within China National Gas Corporation's refining and chemical spare parts network, as well as China's Petrochemical's spare parts resource market.
1992 heralded a transformative era with a strategic shareholding reform, ushering in the official rebranding to Wenzhou Jianqing Industrial Company. This pivotal moment symbolized a new chapter of growth and strategic realignment.
Post-2000, Wenzhou Jianqing Industrial Company embarked on a bold journey of self-reinvention. Building upon years of meticulous product enhancement, they evolved from initially emulating imports to pioneering unique designs and independent R&D. Step by step, they have solidified their esteemed position in the ever-evolving industry landscape.
Product category introduction: Jianqing Industrial proudly presents a diverse array of wear-resistant components, including air valves, piston ring support rings, packing rings, gas regulators (actuators), and check valves. The design ethos has undergone significant evolution, particularly the air valve, which has transformed from its original metal mesh form into a variety of innovative structures such as ring inclined valves, mushroom valves, and infinity valves.
Our esteemed clientele spans the breadth of China's provinces, encompassing industry giants like Yanshan Petrochemical, Cangzhou Petrochemical, and Shijiazhuang Refining and Chemical. We are trusted by influential entities such as the State Pipeline Network, Xinhai Shihua, and Dagang Oil Field, among others. Our reach extends to renowned names like Daqing Petrochemical, Harbin Petrochemical, and Dalian Petrochemical. In the vibrant East China region, we proudly serve Zhenhai Petrochemical, Zhejiang Petrochemical, and CNOOC Daxie Petrochemical, to name a few. Venturing beyond domestic shores, we've made strategic inroads into international markets, exporting to Brunei, Russia, and the Middle East through key partnerships. The horizon is bright, promising expansive opportunities in untapped global markets.
The one-way valve can be installed in any position and direction of the compressor, simplifying engineering design and increasing flexibility. Featuring high dynamic valve characteristics, it can effectively prevent backflow and has almost no wear, reducing maintenance costs
