Test And Drain Valve, K 5,6 (80), Threaded

Its orifice available with different sizes creates a flow equivalent to the flow passing along one sprinkler only and enables tests of alarm devices on the lines for checking purposes in the case of a sprinkler water flow. The orifice diameters of the smallest sprinkler and the test drain valve in the system should be equal. It is also used as a drain valve to discharge water in the piping by changing the position of the valve. It includes a sight glass to observe the flow.
