April 14, 2025 (Liaocheng) – Refrigeration valves manufactured by Shandong Dofun Refrigeration Technology Co., Ltd., located in the Liaocheng Jiaming Economic Development Zone, have been selected for use in the refrigeration system of the luge/bobsleigh track for the 2026 Milan-Cortina Olympic Winter Games, according to information released by the zone. The product quality has received high recognition from the end-user.

In the second half of last year, an Italian client placed an order with Dofun Technology for valves for the refrigeration system of the Olympic sliding track. After several months of preparation and production, the order has now been delivered in full.

“As a Shandong Provincial Gazelle Enterprise, we primarily produce system valves for large-scale cold storage facilities. In recent years, through sustained industry-university-research collaboration, we have gained a technological leading edge in low-temperature alloy materials and multi-functional combination valves. Our products have achieved considerable market share in countries including Russia, Italy, Spain, Egypt, Pakistan, Brazil, and South Africa,” said Wang Chao, Deputy General Manager of Dongfa Technology. He noted that the achievements and reputation gained in the international market over the past years formed the crucial foundation for becoming a supplier for the Olympic Games.

Founded in 2012, Dofun Technology entered the refrigeration industry and found that valves in the domestic sector were largely monopolized by European and American companies. In response, the company invested heavily in R&D, breaking through international technical barriers with dozens of invention patents. It has developed valve products covering the industrial refrigeration sector, including over 30 series of automatic control valves, manual valves, various check valves, and filters. The company also took the lead in formulating domestic industry standards for refrigeration valves. Building on this, Dofun actively expanded into overseas markets, obtaining international quality system certifications including EU CE marking and Russian EAC certification. Its products are now shipped worldwide via maritime routes, exporting to over 100 countries and regions.

Dofun Technology, in collaboration with Liaocheng University, has successfully developed a new alloy steel material capable of withstanding ultra-low temperatures down to -196°C, offering improved impact resistance, pressure endurance at low temperatures, and enhanced material toughness. Its latest multi-function combination valve reduces the need for welding, simplifies installation, and breaks the monopoly previously held by imported brands. The company has also improved the quality and service life of its constant pressure valves while reducing costs, gradually achieving import substitution in this product category. Leveraging its high-end refrigeration valve industrial park, Dofun plans to launch a new production line with an annual capacity of one million units, further diversifying its product range and striving to develop more star products within the specialized industrial refrigeration valve sector.

Since the beginning of this year, the company’s exceptional products and services have earned high customer acclaim, shining in both domestic and international markets and being featured by multiple mainstream media outlets.

Supported by robust technical expertise, sophisticated production equipment, comprehensive testing methods, and full-process management systems, Shandong Dofun Refrigeration Technology Co., Ltd. adheres to its core values of “Starting from One’s Own Heart, Pursuing the Ultimate Good” and upholds the tenets of “Quality as the Foundation, Users as the Priority, Environmental Friendliness, and Technological Leadership.” The company remains dedicated to advancing the quality standards of the refrigeration industry and providing superior products and professional services to both new and existing customers worldwide.
