Thanks - RVAmeche
YOu are right and that is what is my concern. Now from the data sheet - I have reckoned that the 600# valve design parameters are less than that of 300#. However I will not be able to certify my proposed valve as 600# due to this "you fire up the system during commissioning...

Yes - that was equally surprising us, we had requested the customer clarifying this, which they have confirmed the data is correct, and the choice of 600# for these lower condition than 300# is due to piping design (which is complete).
Under this limitation, the above was...
Could some one please advice on the below limitation / proposal
My customer requires a 600# valves (flanged) but the weight of this is approx 30T. Importantly the max design pressure / temperature is less than 300# valve which weigh 9T.
My proposal
1. Offer 600# as a 300# valve This will...
