Its generously sized 1-inch NPT side ports make it well-suited for filling, purging air or sampling geothermal ground loops, and make it easy to add a pressure gauge to the system at the pump. The main valve provides a method for isolating the loop from the rest of the system, simplifying the task of maintenance. The product provides a 1-inch press connection, two plugged 1-inch FIP connections and detachable rotating flange.
The Isolator Select is compatible with popular press tools and has a lifetime guarantee. For more info, visit http://www.webstonevalves.com/IsolatorSelect.
