Review PG-71 in Section I. Two valves may be used on "Y" fitting but they must be independent of each other.

mihir5577   Yee eans a Yee type of tee,
simple enough  you choose a yee because a std  tee will accumulate water so a yee and 2 niples and couplings will separate the 2 sv's from each other
consult your plumbing books or the supplier and they will know you will see.

RE: ASME SEC I, SAFETY RELIEF VALVE

you will also need to confirm the reactions from the releif valve will not overtune or damage the wye connection- this might be done by placing a saddle support under the valves.
