Trim for 10" swing check valve
Trim for 10" swing check valve
(OP)
My clients requirement is 10" swing check valve with A216 WCB body & Trim 1. I supplied valve with A216 WCB + 13% Cr for the trim. My client has rejected informing that he asked for trim 1 but I have supplied trim with A216 WCB + 13% Cr. Can any of you give me an idea how I can convince my client to make him accept the supplied valve

Trim 1 is 13%Cr seat and disc. You have to demonstrate that there is a 50Hb differential between the seating surfaces and that the nominal hardness is 250.
So if your disc is 250 HB the seat ring must be 300HB or more.
Once you prove this it's possible your customer may accept the valve.
