API 6D Check Valve Trim
API 6D Check Valve Trim
(OP)
Does anyone know the "standard" trim for API 6D check valves? I'm used to B31.3 specs where we typically specify API Trim #8 but I'm being told that is not the case for API 6D valves. Can anyone shed some light on this?

I'm not worried about corrosion, frankly, because of the nature of the service. It's about as benign as you can get, but my client is searching for anything and everything to keep costs down and consequently I need to specify the least expensive valves I can while still maintaining the integrity of the system.
