O Ring 6in Mod E
Reliable Models E and E3 Alarm Check Valves act as a water flow alarm device in wet pipe sprinkler systems. The design allows for installation under both variable and constant supply pressure conditions. When water flows into the sprinkler system due to the operation of one or more automatic fire sprinklers the alarm valve opens, allowing continuous flow of water into the system and transmission of an electrical or mechanical alarm. The valve may be installed in either the vertical or horizontal (clapper hinge on top) position. The E4 Alarm Check Valve trim includes a 2” (50mm) Reliable Model TD Test and Drain Valve with an integral K4.2 (60 metric) test orifice.
