Brightech® Deluge valve is a solenoid control on-off valve which either opens or closes upon receiving an electrical signal to the solenoid pilot control to provide water flow to the fire protection sprinkler system. This valve consist of a Actrol main valve, a three-way solenoid valve and an auxiliary pilot valve. This pilot control system alternatively applies pressure to/or relieves pressure from the diaphragm chamber of the main valve. it is provided either normally open or normally closed. pilot system can be hydraulically , pneumatically or manually operated.
Energized the solenoid valve pressurizes the diaphragm chamber of the three-way auxiliary pilot valve. The pilot valve then shifts to relieve pressure from the diaphragm chamber of the main valve , allowing the main valve to open fully and admit water through the main line. The valve may also be opened by utilizing the manual override ball valve on the bonnet , which allows opening of the main valve regardless of solenoid pilot activation. The valve closes when the solenoid valve is de-energized.
