Fleu Group, founded in 1990, specializes in the production of DIN valves and exports them to Germany, making it one of China's leading manufacturers in this field.

It specializes in the development of innovative designs, engineering excellence, and produces according to DIN and EN Standards. 

It is the first customer of TÜV to obtain the AD-W0 Certificate for castings and TA Luft Certificate for valves. 

Its major products encompass DIN Gate, Globe, Check, and Ball valves made from carbon steel, stainless steel, gray iron, and ductile iron. These products have been utilized in a diverse range of applications within the gas, oil, refining, and chemical industries. 

The valves are manufactured in a single assembling factory, our own stainless/carbon steel foundry, and our own machining shop. The sales offices, agents, and distributors are located in Europe and China. 

Through extensive and effective cooperation and technical communication with numerous German enterprises and Chinese institutes, Fleu Group has established a leading position in the production of DIN valves. To provide more convenient product sourcing to its customers, Fleu Group has expanded its product range to include ANSI valves since 2017, in collaboration with a partner valve manufacturer. Fleu has maintained a valve storage facility in Germany since 2011. 


To maintain product quality and delivery reliability, the company has implemented a Poka-Yoke system in production. This uncompromising quality requirement, combined with just-in-time delivery, has dramatically improved its production efficiency and reliability.

Fleu Group aims to become one of the world's leading DIN valve manufacturers. Fleu Group's strategies focus on high performance, absolute reliability, and environmental friendliness.

Its own foundries, as well as its cooperative foundries, possess PED and AD2000 W0 certificates from TÜV. All Fleu valves comply with TA Luft specifications. Additionally, all Fleu foundries and factories utilize the latest technologies.

We always regard honesty and trustworthiness as the foundation of our cooperation.
