Yuanda, Hugong, Meike, Gongnai, Liangzheng – their valves
Thread Content
The valves specified in the process package are required to be from brands such as Yuanda, Hugong, Meike, Gongnai, or equivalent ones, but actually Liangzheng valves were supplied. How does Liangzheng compare to these other brands? Is it the same?
For simple process control, switch valves are used; they aren’t turned on or off even once a year, so there’s no real difference. However, there is a significant difference in weight alone between large and small manufacturers of globe valves and gate valves; no further comments are needed on other aspects.
Oh oh oh, I guess I get it now. The manual valves in use on site, whether those that are turned on and off frequently or less frequently, are almost all from Liangzheng. Over an 8-month period, 4 valves in the amine liquid carbon dioxide removal system leaked – there were ball valves, globe valves, and gate valves; other systems also had faulty valves.
