Changing Thermo relief valve from 145 to 165

I have a prochem legend XL. The thermo-relief valve at 145 bypasses to much water and i fill my recovery tank far too quick. I wonder if I could switch to a 165 valve and not damage the seals. Part of the problem is the van is insulated (I'm in Canada) and heat builds up. Also considering putting some heat shielding on or around the water box to get less bypassing unnecessarily.

Should be ok. Just about all pumps can handle 165 degree water although that is generally the hottest you can use without damaging the pump unless you have high temp seals.
