NRS VALVE

Used in water-based fire suppression systems as an equivalent of the Supervisory Switch Butterfly Valve and the OS&Y Rising Stem Valve to provide zone water flow control. It is suitable for pipelines buried underground in outdoor areas against the risk of freezing (e.g. hydrant lines). Like the Supervisory Switch Butterfly Valve and the OS&Y Rising Stem Valve, its open and closed positions can be monitored, but this is done mechanically rather than with a switch box.
