If the pressure is getting up to the relief valve setting (probably 30 PSI, possibly 50), the pressure reducing valve may be overfeeding water or may need adjusting, the PRV bypass (If it has one) may be leaking by, overpressurizing the system, or the expansion tank if it is a standard compression tank, may be flooded not giving any air pocket for expansion.
Turn the valve off to the tank and drain it. Open it back up and let it refill. There will be an air cushion now, but the tank may have a leak in it or the line feeding it.
This is assuming it is a water boiler.

When you replaced the valve did you use the proper thread compound on the new valve. Depending on the temperature of boiler system you may need higher rated temp compound?
