Recently, the Shandong Provincial Development and Reform Commission issued the "Notice on the List of Newly Recognized (Batch 32) and All Shandong Provincial Enterprise Technology Centers in 2025" (Lu Fa Gai Gao Ji [2025] No. 801). The Technology Center of Qingdao Jingrui Machinery Manufacturing Co., Ltd. was successfully selected, marking that the company's R&D strength has once again been recognized by the provincial authorities, adding a "strong engine" to innovation in the field of fluid control.
The Shandong Provincial Enterprise Technology Center is not only a key engine for enterprises to tackle "bottleneck" technologies, capitalize on policy dividends, and enhance market competitiveness, but also a benchmark for leading industrial high-end transformation and driving collaborative innovation across the industrial chain, and a reserve force for connecting with national enterprise technology centers.
As a national high-tech enterprise, a national specialized and innovative "little giant" enterprise, and a Shandong provincial gazelle enterprise, Jingrui Machinery's R&D DNA is deeply ingrained in its development. To date, the company has obtained 139 patents (including 17 invention patents), established a Shandong Provincial "One Enterprise, One Technology" R&D Center, and built seven laboratories focusing on fatigue, performance, and materials, equipped with internationally advanced equipment such as imported German spectrometers and coordinate measuring machines, constructing a complete technical support system from R&D to testing.
Behind this recognition lies the company's core strength in continuously tackling "bottleneck" technologies. Addressing the pain point of relying on imports for high-end valves, the team has successively developed key products such as nuclear industry gate valves and pharmaceutical-grade diaphragm valves. They have also overcome a challenge in the new energy lithium battery field—developing a membrane plug valve specifically for electrolyte filling equipment, effectively solving the problem of electrolyte crystallization, leakage, and blockage. This valve is corrosion-resistant, has excellent sealing performance, leaves no residue, and has a lifespan exceeding one million cycles, reducing costs for customers by over 400%, breaking the foreign monopoly, achieving "domestic substitution for imports," and leading industry development. In the field of intelligent technology, the company has equipped industrial valves with a "brain." Their independently developed intelligent regulating valve features dynamic compensation algorithms for pressure compensation, pulse width modulation, and PID regulation, achieving a control accuracy of 0.1% (an error of only 1 drop per thousand drops of liquid). It can automatically respond to temperature and pressure signals to adjust flow rate, with performance comparable to international counterparts.
This R&D strength also stems from the deep integration of "industry-academia-research-application." The company has established R&D centers in both Shanghai and Qingdao. The Shanghai team focuses on cutting-edge solution design, while the Qingdao team achieves "from 0 to 1" technology transfer. Furthermore, it collaborates with universities such as Shanghai University of Science and Technology and Qingdao University of Science and Technology to continuously build up its innovative momentum. Currently, the company's products cover 19 industries, adapting to diverse scenario needs through technological innovation. Its products are exported to 82 countries and regions, gaining recognition and use from numerous domestic and international customers.
This recognition as a Shandong Provincial Enterprise Technology Center marks a new starting point for Qingdao Jingrui Machinery. In the future, the company will continue to focus on the "high-pressure, high-frequency, and high-precision" valve field, increase R&D investment, promote intelligent transformation and digital transformation, and use the technology center as a platform to become a leader in systematized solutions for fluid process control systems. It strives to become a benchmark in the domestic and international valve industry, deeply practicing its original aspiration of "making good valves for the world."
