OPERATION

The basic control valve [1] used in this deluge system is a direct sealing elastomeric diaphragm, hydraulically operated control valve engineered specifically for fire protection systems. The system includes a 2/2-way N.C. solenoid as the interface between the fire alarm control panel - monitoring heat, smoke or flames - and the deluge valve.

In the stand by position, the deluge valve is held closed by the upstream water pressure, trapped in the valve’s control chamber. The water pressure enters the control chamber through the priming Line Ball Valve [2], a Y-Type Strainer [3], a Check Valve [4] and a T-Restrictor [5].

Under fire conditions, a fire alarm control panel energizes the 2/2-way N.C. Solenoid [9] (or de-energizes the coil of a continuously energized ED 100% normally open solenoid for SIL 3-4 rated systems). Water is drained the deluge valve’s control chamber through the 2/2-way N.C. Solenoid. The deluge valve opens instantly and allows water to flow the pipeline and through the open sprinklers over the protected area.

Manual emergency actuation is enabled by opening the Emergency Manual Activation Valve [6]. The deluge valve opens instantly and allows water to flow the pipeline and through the open sprinklers over the protected area.
