I would like to ask the experts: Are valve sizes based on universal standards? The valve models are the same across all manufacturers, but are the dimensions the same? For example, for pneumatic on-off valves with a diameter of DN150, pressure rating of PN16, and made of 304 material, is the size of their valve body the same as that of the Q41H-16P (DN150/304) valve body?
The size of a valve, that is, its structural length, is **standardized**. However, regarding whether the length of the pneumatic on-off valve you are referring to is the same as that of the Q41H-16P ball valve, there is one missing prerequisite: it is not clear whether the pneumatic on-off valve in question is of the pneumatic ball valve type or the pneumatic globe valve type. If it is a pneumatic ball valve, then according to the standards, its structural length will be the same as that of the Q41H-16P ball valve. On the other hand, if it is a pneumatic switch globe valve, the situation is different. This standard can be found; our company’s product catalog contains tables with the parameter dimensions of most common valves for reference.

More or less is fine; the key is to have a space where it can be installed. Length doesn’t matter, but the direction of the handwheel and the die need to be taken into consideration.
