Alarm Check Valve Model C-1

The Viking Model J-1 Alarm Check Valve serves as a check valve by trapping pressurized water above the clapper and preventing reverse flow from sprinkler piping. The valve is designed to initiate an alarm during a sustained flow of water (such as the flow required by an open sprinkler) by operating an optional water motor alarm and/or alarm pressure switch. The valve is made suitable for use on variable pressure water supplies by adding the optional retard chamber to the standard trim.

Features

Ductile iron body for less weight and extra strength.

Rubber-faced clapper hinged to access cover for quick removal and easy servicing.

All moving parts can be serviced without removing the valve from the installed position.

With the cover/clapper assembly removed, clapper rubber replacement requires removal of only one screw.

External by-pass trim to minimize clapper movement and false alarm.

Trim allows installation of optional non-interruptible pressure switch to activate an electric alarm panel and/or remote alarm.

Can be installed on constant or variable pressure water supplies.

Can be installed vertically or horizontally, with the access cover facing up.

Valve housing tapped for inlet and outlet pressure gauges, alarm devices, and system main drain.

Trim includes alarm test valve for testing alarms without reducing system pressure.
