ASME I Safety Valves

[Valving]

I am trying to prepare vendor list for asme I safety valves manufacturers.
So far I located Weir, Crosby, Sapag, Leser, Bopp&Reuther, Sempell etc.
Do you have experiences with them?
Would you advice others as well?

On what type of system are you installing these valves? Safety valves are rated differently for steam, hot water, or other medium such as air , refrigerants, propane, etc...
