For the outer surface, materials other than stainless steel require painting; typically, two coats are applied – an undercoat to prevent rust and a topcoat. There are also requirements regarding the thickness of the paint film; generally, the dry film thickness should be around 300 microns. If the environment you use is not highly corrosive, ordinary valves available in China will suffice

Valve painting regulations aren’t that strict in China, right?

They are all imported valves. I would like to know the specifications or standards for corrosion protection of these valves, as such information can be used to convince manufacturers~~~

There aren’t many standards regarding the painting of valves, right? Are you in charge of procurement or technology? If you have such strict requirements, you should consider the quality of the valves – things like whether they leak or not, and how well they can be adjusted

Corrosion protection requires specific wall thickness specifications; the requirements regarding painting are not very strict – painting is provided according to the customer’s requests. Materials such as stainless steel and copper alloys are generally not painted. Requirements such as color codes and thickness are all based on the customer’s specifications; however, there are also regulations regarding painting, which can be found on Baidu. Purchasing valves are basic tasks. By the way, as a promotion: if you are considering domestic manufacturers, you might want to give us a look. We manufacture copper valves, valves made from special materials, as well as gates, stop valves, ball valves, and butterfly valves with custom designs. Phone number: 13289966270.

When purchasing, there are no special requirements regarding the engraving on the valve body or nameplate; the factory logo is sufficient. What other quality documents are needed? The packaging is the same; no special requirements, just the factory logo. So, one needs to be careful in all cases.
