1. DESCRIPTION

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.
