The Victaulic® FireLock® Series 751 Alarm Check Valve prevents the reverse flow of water from the wet sprinkler piping system to the inbound water supply. The valve is trimmed with a water bypass line to allow pressure surges to enter the system, preventing false alarms. This valve package ships assembled and factory tested. Valve comes as pictured and does not include main drain valve, pressure gauges or water flow alarm.
