A very common zone valve is 24V and .3A. (Be sure to notice the little decimal point dot in front of the 3.) Since volts x amps = VA, multiply 24V by .3A, and get 7.2VA. We're getting close to how many of these zone valves we can put on a 40 VA transformer.Not exactly the correct way to wire a zone valve. Those wires go to what is called the 'end switch'. That switch closes when the valve opens, and signals the circulator to run and the boiler to fire. If that switch is not used, and the valve fails in a closed position, your circulator pump will run into a dead head and quickly self-destruct.Consider that the zone valve is nothing more than a mechanical water flow valve on a loop of hot water heating pipe that. 1. responds to a thermostat's call for heat. 2. opens to allow hot water to flow through the zone. 3. turns on the circulator pump once the valve is open.
