In a sprinkler system, it is used to test the system and expel unnecessary liquid from the system.
Advantages: The valve body has a built-in sight glass, and a single valve is enough to discharge water from the pipeline.
When selecting test and drain valves, pay attention to the pipe diameter. At the same time, the diameter must be the same as the orifice diameter of the sprinkler.
