Description
BERMAD Hydraulically Controlled Deluge valve with 5D trim is actuated by an HRV - Hydraulic Relay Valve
(26B), which permits local release of top chamber pressure (instead of the usual remote top chamber release by
the hydraulic release system), in order to ensure quick opening even when the release device is distant.
The Deluge Valve requires a wet pilot line system including hydraulic releases.
The HRV (26B) is normally held closed by pressure maintained in the hydraulic release system.
The 5D trim may also use a Normally Closed hydraulic release system with thermostatic releases and/or fixed
temperature releases to release water pressure directly from the Deluge Valve top chamber.
In fire conditions, operation of a releasing device on the hydraulic release system causes pressure in the release
system piping to drop, causing the HRV to open, releasing to the atmosphere trapped water pressure from the
top chamber and opening the Deluge Valve, allowing water to enter the system piping.
The releasing device in the Normally Closed hydraulic release system holds the pressure in the top chamber of
the Deluge Valve. The opening of the device in a fire condition releases trapped water pressure from the top
chamber, opening the Deluge Valve allowing water to enter the piping system. Water will flow from any open
sprinklers and/or spray nozzles on the system.
Deluge systems are commonly used where, when the system operates, it is desirable to simultaneously spray
water from all open sprinklers and/or nozzles on the system.
