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.
