Dry Barrel Hydrant (Open/Close Indicator)
This large-size hydrant is mostly used in plant facilities and fire truck or even monitor can be installed. Large quantity of firefighting water can be used, and even in the installed state, the upper cover and the housing can be removed to replace the internal parts.
Vibration owing to the firefighting water was minimized on use, and drainage of
internal firefighting water is enabled quickly after use.
Unlike other existing hydrant, it can always check the open/close state, and on opening,
the discharge pressure can be checked for safe use.
