So, it bypasses the switch that sends full power to open the valve and gets what it needs, and sends the rest down through the heat coil of that zone valve. This works fine until there is a call for heat and that taco valve opens. When the valve gets near full open, it interrupts current by opening a switch, so the heater coil doesn't overheat.

Globe: Water faucets (taps) are examples of globe valves. When you turn the handle, you screw a valve up or down and this allows pressurized water to flow up through a pipe and out through the spout below. Unlike a gate or sluice, a valve like this can be set to allow more or less fluid through it.
