I have a question regarding the paint on the valve surface

The paint used on exhibition items is of very high quality; its surface is quite smooth. It’s generally used on butterfly valves and similar devices. What type of paint is this? A few days ago, I purchased several bellows globe valves, and the customer was furious with me – after installing them and using them, the paint on them all peeled off. . . . I heard that epoxy resin paint is quite effective; may I ask, what kind of paint is suitable for use on valves? How many types of painting processes are there? Will it be easier to peel off with the paint applied? Thank you all, experts! ! :Q This question is so annoying, please help!
Passed by the second floor of Xue*, got it easily
I don’t understand, but if that’s the case for brand-new valves, then the manufacturing process must be poor.
The 1,600-degree silver-gray high-temperature paint tends to peel off easily； 2. For general painting, Kunshan Yongji (Taiwan Hongpai) can be used; the specific choice depends on the operational conditions and the required corrosion resistance period ； Foreign customers can use “AkzoNobel”, “Xuanwei” etc
This post is ambiguous; it can only refer to problems with certain manufacturers, but you’re generalizing and affecting an entire industry. Wenzhou-based valve manufacturers hold a large share of the national market, and I believe that the quality of their products is generally good (including the paint used on them)
The valves we have used are of good quality; if the paint quality is good, then the opposite is true – you get what you pay for.
There are various reasons why paint peels off: the quality of the paint itself, and whether the surface was properly prepared before painting Is there any oil, dust, etc.?

Could it be that the surface of the valve wasn’t properly treated? Also, check if there’s something wrong with the primer~
The ease with which paint peels off is also closely related to the surface treatment of the valve body. First, clean the grease and dirt from the surface of the valve body, then apply an anti-rust paint coat. Once it has dried completely, apply the topcoat and let it dry naturally!
