GB/T 12237 Ball Valve

Thread Content

Does the standard GB/T 12237 cover both non-metallic and metallic sealed ball valves? Is it only applicable to non-metallic sealed ball valves? I would appreciate some guidance from experts, thank you!

When GB/T 12237 was formulated, there were no specific detailed regulations for metal seals; however, metal seals could refer to GB/T 12237. Later, GB/T 21385 \"Metal Seal Ball Valves\" was established, which can be consulted.
