For the quality of workwear in Wuxi, it’s best to have them produce it themselves. It's hard to say about outsourcing. Also, Zigong’s high-pressure valves are of good quality; they were acquired by Tyco.
In fact, if domestic options are considered, Wuzhong Instruments, Shanghai Ziyi, Nales, and Xi’an Instrument Factory are all viable choices; these companies have a track record of being used in many chemical plants across the country, and their after-sales service is relatively reliable.
