Founded in 1985, the company set up a boiler descaling treatment station and specialized in boiler cleaning services from 1985 to 1989.

In 1990, the first‑generation “Zhongquan” automatic exhaust valve for heating boilers was developed. It filled the gap in the domestic industry and solved the technical difficulty of steam‑water explosion accidents in heating boilers. The product passed the technical appraisal organized by the Boiler and Pressure Vessel Inspection Center of the former Ministry of Labor.

In 1991, the first “Zhongquan” horizontal automatic exhaust valve for heating pipelines was successfully developed, once again filling a domestic industry gap. It became a pioneering standard‑compliant exhaust valve product in China at that time, delivering reliable performance for residents and earning public trust. The valve resolved difficulties in residential heating circulation and brought warmth to households in winter.

From 1992 to 1994, the Boiler Bureau of the former Ministry of Labor issued an official document for the mandatory promotion of automatic exhaust valves for heating boilers. Supported by the Bureau, the product opened up the domestic market, and provincial authorities across China successively issued corresponding promotion notices.

In 2003, the company developed its first compact vertical automatic exhaust valve, overcoming the limitation of narrow installation space for exhaust valves and achieving miniaturization in product design.

In 2005, the aluminum‑alloy octagonal automatic exhaust valve was independently developed, solving the problem of shell corrosion during service.

Zhongquan launched the R&D of copper automatic exhaust valves in 2006. Pilot production was completed in 2010, ending the domestic blank in the manufacture of high‑quality copper exhaust valves.

Since 2010, the company has carried out diversified development and new‑product exploration. It has successfully developed geothermal filter valves and craft decorative panels one after another.

In 2012, the company developed the world’s smallest spring‑loaded sealing automatic exhaust valve with world‑leading technology.

Registered trademark “Zhongquan” was recognized as a Famous Trademark of Jilin Province by the Jilin Provincial Bureau of Quality and Technical Supervision starting from 1991 and has retained this honor for many years.
