Control valve
Thread Content
May I ask what domestic manufacturers of control valves there are, and what are the brands?
Many, it’s hard to say; you can look it up online and make your own judgment.
For control valves, we used those from Wuzhong the most.
Thank you. Are there any other brands with quality similar to his?
Gongzhuang and Wuzhong are quite good options; there are also many other small factories such as Shanghai Akka, Shanghai Chuanhu, Zhejiang Bell, as well as those in Fuyang and Yueqing. Among the imported brands, we have Fisher, Samson, and Wedge, with price differences of up to ten times.
Thank you, I’ve learned something new. There are also imported brands such as Meissonier and Samson. Hehe, we use products from Shanghai Automation Factory No. 7. I’ve heard of Wu Zhong. Are there also imported tooling options? I’m not sure about the rest. Hehe, thank you
The KOSO quality is quite good. We use it mainly with natural gas, hydrogen, boiler feed water, and steam. It’s been in use for over 9 years now, and aside from a few valve positioners that malfunctioned, there have been no major issues.
It can be used; it doesn’t require much technical skill.
Imported products are now more expensive, while domestic alternatives are a viable option. At present, some design firms and manufacturers are attempting to localize certain high-temperature and high-pressure equipment used in hydrogenation projects.
