How can I eliminate excessive flow from my pressure valve at the water heater?

do you mean the emergency temperature/pressure relief valve on the side or top of your hot water tank? You should have no flow out of this valve. if so replace it immediately.

if you are talking about excessive pressure thru out your hot water system or thru the whole house, then you should install a pressure reducer at or near the water main.

have you tested the pressure in your home? It should be no greater that 80 psi.

If you have a pressure reducing valve on the system, this could be caused by thermo expansion, if this is so, then installing a thermo expansion tank will be needed to solve this problem.
