Description

Test and Drain Valve is used to conduct testing and maintenance on sprinkler systems. With the orifice in different sizes inside, it 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 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. There is a sight glass to observe the flow.
