How does a taco zone valve work.

Heavy-cast brass body with sweat connectors. Bottom is made of beryllium copper helping for a virtually leak-proof operation. Globe valve design with a resilient seat for tight shut-off. Zone valve features its own thermostat. Quiet heat motor function that is not constantly energized while the valve is open. Note: Product may vary by store. Since there's a common circulator pump and controls one might naturally suspect either the zone valve itself ( a bad connection, loose wire), or a bad control module in the Taco master zone control. Take a look at the system temperatures and at whether or not you are using domestic hot water when this short-on-zone problem is occurring. Out of the side port added a small length of pipe to a 90 degree fitting and then up to our hot water pipe. Straight out the top of the T added pipe to just below ceiling and used a 90 degree fitting with a 1/8 inch female port to fit the hydro vent and plugged the other side. Put plastic tubing on the air vent and ran it to the outside of wall.Ensure that all wires are properly connected and tightened in the 571 2 zone valve. Use a screwdriver to secure any loose terminals and ensure a solid connection. Loose connections can cause intermittent or complete loss of power, resulting in heating or cooling issues. 2.
