Taco Zone Valve Mechanism

This video explains the valve mechanism of the Taco Zone Valve model 571-2.

I replaced an old valve that leaked and got stuck with this piece. Before installation, I unscrewed the metal plate that holds the valve in place because I was curious to find out how it works.

Here’s the official instruction sheet on how to replace or clean the valve seat assembly: http://www.taco-hvac.com/uploads/File...
