Ball valve PN10
Thread Content
Now, a national standard ball valve with PN10 specification is needed. After checking the standard GB/T 12237 for ball valves, it was found that these valves start at PN16 level; so does that mean there are no ball valves with PN10 specification available? I would appreciate some guidance from experts, thank you!
Solution: 1. The product standards are based on GB/T 12237; the structural length is in accordance with GB/T 12221; the connection flanges follow GB/T 9113； 2. Designed directly in accordance with GB/T 12224. 3. If it is made of iron, it can be designed in accordance with GB/T 15185
GB/T 12224 is the basic standard for valves; the PN10 mentioned here is likely intended for butterfly valves, right? Should G/T 12237 and GB/T 12224 be used together? Please give your advice
GB/T 12224 is the basic standard for valves; essentially, all valve products that exceed the specific product standards can be designed and manufactured in accordance with this standard. It can be used in conjunction with product standards. The original poster did not want to switch to butterfly valve products, so this should not be part of the discussion.

Thank you, expert. It seems that PN10 isn’t a standard product either
