    There is no need for a separate automatic fire detection facility, and when more than one sprinkler head operates, the clapper opens to send a fire alarm, and extinguishing water is discharged to the fire point.

Flange Type

Accurate detection is possible by directly detecting the movement of running water and delivering an alarm.

As an option, the test valve and sight glass are integrally attached to the drain valve, greatly reducing the construction cost and thus high economic efficiency.

You can choose the left or right type of drain valve depending on the piping.

High- strength domestic casting (GCD 450) is used to increase durability. 

The weight is reduced and handling is easy when it is installed.
