Fire Protection System
- Deluge valves are used in deluge fire sprinkler systems to deliver large quantities of water over a large area in a short period of time. The deluge valve is triggered to open by smoke or heat detection system which is installed in the same area as the sprinklers. The pipes in deluge systems are empty until the deluge valve is activated to deliver pressured water to the sprinklers.
- A pneumatically actuated deluge valved can be used for automatic or manual operation. The dry pilot line, which is pressurized with compressed air or nitrogen, works as a thermal detector equipped with a fixed temperature release. When one or more of the sprinkler heads on the pilot line fuses, or when a manual release station is operated locally or remotely, the deluge valve opens and water flows from all open sprinklers and/or nozzles on the system.
- Electric activation of the deluge system requires a solenoid valve actuated by a control panel with heat, smoke, or flame detectors. When the detection system operates, the control (fire alarm & releasing) panel energizes the solenoid valve to open. When the solenoid valve is actuated to open automatically or manually, or when a manual release station is operated locally or remotely, the deluge valve opens and water flows from all open sprinklers and/or nozzles on the system.
