Only three things make this valve discharge:

Excessive water temperature (212 degrees) excessive pressure (150psi ) or a weak spring.

Since you replaced the valve, let's rule out the last cause. You would likely notice if the heater temperature were above 212 degrees so I recommend we go to the last and most common cause.

Check the water pressure coming into the home. It should not be above 70psi. If it is you need a pressure reducing valve on the main service at which time you will also need to install an expasion tank on the cold water feed to the water heater. It should be install on the downstream side of the heater's shut-off valve. If the pressure coming into the home is reasonable, install the expansion tank anyway and your problem will go away.
