Dear EnergyMix,
I did not get a clear advise from the members of this forum. hsbcn sent me a link to trims, but it mentions that trim 10 is 316SS. My manufacturer is offering me an overlay of 316 & not a solid 316. My question is if we can accept this overlay. If you can help me, please advise...
I have attached the drawing of check valve. It looks like bolted bonnet but my manufacturer informs it is a pressure seal bonnet. Can any one explain to me whether the atatched valve is with bolted bonnet or pressure seal bonnet
Many thanks hsbcn, my specs says 316SS only for wedge, stem & seat & does not mention forgining or casting. Please dvise.
As regards to stellited seat, I will akk my manufacture to remove that as it is not necessary.
