Is there a safety valve gauge?

I don't know if you have ever met this situation: for example, the minimum diameter of safety valve is dn40, and the DN50 safety valve is selected. But some manufacturers have produced DN50 safety valve, the minimum is dn32, more exaggerated, some are dn25, and there are no rules for safety valve.

Safety valves have specifications and standards, but the specific size is better than looking at the valve sample manual, most of which are finalized. Generally, the throat diameter of full-open type is two gear smaller than its diameter, and the throat diameter of micro-open type is one smaller than its diameter.
