The fine chemical industry starts with basic chemical raw materials and undergoes multiple precise synthesis and separation purification processes to produce chemicals with specific functions, high purity, and high added value. Each product has a small scale and there are over 100,000 varieties. It focuses on "specific functions, precise performance, and clear application scenarios". 

The complex and diverse operating conditions in the fine chemical industry place very high demands on valves. Conditions involving high temperatures, high pressures, and corrosive media require special components and solutions.
