How to determine whether it is a valve with an imported inlet or a domestically produced one
Thread Content
I would like to ask the experts: for various types of equipment, how are valves such as single-seat valves, butterfly valves, and on/off valves classified, and are they imported, produced through joint ventures, or made domestically? I hope that experts will use quantitative parameters such as temperature, pressure, pressure difference, medium, flow rate, diameter, etc., rather than saying that certain factors are important. Thank you!
There shouldn’t be any strict requirements for this; it all depends on whether the money fits
There is no strict requirement, but design firms or clients usually have some reference standards. At most, one can find out which joint-venture or domestic brands are performing well, and then make a flexible choice accordingly

The reference standard is the professionalism of the brand’s valves. There are also the preferences of the property owner or the design firm. Generally, it is the case that a company or group purchases products of the same brand on a long-term basis, which facilitates maintenance and upkeep
The idea behind this topic by the original poster is good, but there is no solution at the moment. Whether it is imported may or may not be related to all the considerations you mentioned above
It mainly depends on the owner; the design institute will consider the importance of the valve (for example, whether its failure could lead to safety hazards or merely affect production), and then recommend whether to use imported or domestic valves. However, there is a significant price difference between imported and domestic valves, and whether to adopt one option or not depends on whether the owner has the necessary funds
