The water treatment industry is a fundamental sector that ensures water resource security, controls water pollution, and promotes the circular economy. It covers the entire process from raw water purification to industrial water treatment, municipal sewage treatment, reclaimed water reuse, and seawater desalination. Its core value lies in balancing "water resource supply - pollution control - recycling utilization", supporting industrial production, urban development, and ecological protection. The key difference from traditional water conservancy projects is that it focuses more on "precise water quality control" and "value-based utilization". 

The high-cleanliness automatic control valve, pipe fittings, pipelines and accessories control system units manufactured by Yiteng have been successfully applied in various process technologies and related fields.
