My home has a gas furnace with forced hot water base boards. It's relatively new 2003.
The problem is it has Taco esp zone valves 3 zones all have been replaced at least once.
The HVAC company that did the original work replaced them saying Taco improved the motor. Well I have 2 burned out motors that can't turn the ball valve.

What should I do replace them with the same or get a new valve system?

Thanks in advance
