Zurn Model 1-FTD-K56 Fire Test and Drain valve (1") provides for required water flow testing and draining of a sprinkler system with one valve. In the test position this valve simulates flow of a single sprinkler with a 5.6 K Factor orifice. The drain position allows unrestricted flow for rapid draining of the system. Clear sight glass plugs facilitates visual inspection of water flow through the valve.
