Are the nominal lengths of plastic valves and metal valves the same?

For the same specifications, are the structural lengths of plastic valves and metal valves the same? :)
Plastic valves do not have standard structural lengths, and these vary among different manufacturers
Refer to standards such as GB/T 28494 for thermoplastic globe valves and other related plastic valves.
If the materials are different, the specifications will likely be different as well
Valves of different types certainly have different structural dimensions
