 These valves are used to carry out testing and maintenance on sprinkler systems. Thanks to the orifice inside, available in different sizes, they create a flow equal to the flow through just one 

sprinkler, allowing the alarm devices on the lines to be tested for the case of a single sprinkler water flow. 

The orifice diameters of the smallest sprinkler in the system and of the test and drain valve must be equal. By changing the valve position, they can also be used as a drain valve to 

empty the water in the pipes. A sight glass allows the flow to be observed.
