There is no difference between the minumim wall thickness requirements of API 603 and ASME B16.34.
Just because a valve complies with ASME B16.34 does not mean that it complies with API 603.
There are many requirements listed in API 603 that are not covered by or addressed by ASME B16.34.
Could anyone direct me to software programs which can perform the calculations for spherically dished covers (bolted heads) as required by ASME section VIII Div. 1 Appendix 1 paragraph 1-6. Figure 1-6 (c).
Thanks in advance for your help.

Does anyone know of a casting material specification which is equal to P92 pipe or the ASTM A-182 F92 forging specification?
Thanks for your help in advance.

In my early years as a valve R&D lab. engineer, I used a product called Stresscoat from the Magnaflux Corp. I don't know if it's still around. You might try talking to some testing lab.

These classes are no longer associated with a pressure/temperature rating but rather with a pipe wall thickness or schedule. See ASME B16.11 Table 2.
If you would like to go back in history and see the original class to p/t relationship you'll need to go to the 1966 edition of ASA B16.11.
Here are two more suggestions.

I’ve worked with both companies and was very happy with their work.
The final safety factor for the valve shell(body & bonnet), in regards to internal pressure, is in the hands of the valve designer. For steel valves, ASME B16.34 and API 600 or API 602 (and others) stipulate minimum wall thickness requirements based on valve size and pressure Class. These...
I have a requirement for a threaded gate valve stem and threaded bushing that is to be aluminum bronze. The stem will be forged or bar stock and the bushing will be cast. What would be the best UNS number selection of alloy for the stem and bushing that would prevent galling of the threads...
