Which brand is good for control valves!
Thread Content
The company needs to select a batch of control valves from top domestic brands! Please recommend some good options from those who know more – something that can be used stably over the long term! {:2_33:}
Wuzhong, Chuanyi, and Shangyi are all quite okay
Wuxi Workwear, Shanghai ValveTech, Jilin Chuanghe Fluids, Wuzhong Instruments, Chuanyi
It is necessary to provide the operating conditions and technical requirements in order to give a recommendation; for example, there are fluorinated lining control valves that are resistant to corrosion, as well as control valves made of ordinary materials. The manufacturer’s best products also vary.
Domestic brands: Zhejiang Sany Fang, Wuzhong Instruments, Chuanyi. Stable quality. For after-sales service, I think Chuanyi and Wuzhong Instruments are better.
Wuxi Industrial Equipment, Wuzhong Instruments, Chuanyi, and the Seventh Factory of Shanghai Automation – but it’s not necessary to use only top-tier products; many people opt for them mainly because instrument engineers want to shirk responsibility and be lazy.
Chuanyi, Wuxi Workwear, Shanghai Dacheng
For joint-venture brands: FISHER (Tianjin factory), FLOWSERVE (Suzhou factory), KOSO (Wuxi factory) 【Fisher and Flowserve do not offer butterfly valves】 For domestic brands: Wuxi Smart, Wuxi ADI, Wuzhong Ningxia Valve Factory (the products from Wuzhong Shanghai are of average quality). At the same time, Wuzhong has been acquired by CONSEN; it’s unclear whether it is appropriate to position it as a domestic brand. All these manufacturers are capable of producing valves for demanding operating conditions. If the operating conditions are normal (medium to low pressure, no venting, no corrosion), then many manufacturers can meet your requirements.
