FP 400E Installation, Operation
&
Maintanence
Installation
Proper operation of the FP 400E Deluge Valves depends
upon their trim being installed in accordance with the
appropriate trim configuration.
Notes:
■
Wet pilot height should not exceed “Maximum
Elevation Above Valve" (see data for specific model).
■
Any deviation in trim size or arrangement may
adversely affect the proper operation of the deluge
valve.
■
All the pilot system devices, must be UL Listed and
compatible with the particular deluge system. Refer
to current “UL Listed Fire Protection Equipment
Directory”.
Warning: The deluge valve and trim must be installed
only in areas where they will not be subject to freezing
temperatures.
Installation Instructions
1. Allow enough room around the valve assembly for
any adjustments and future maintenance.
2. Before the valve is installed, flush the pipeline to
remove any dirt, scale, debris, etc. Not flushing the
line may result in the valve being rendered
inoperable.
3. Install the valve in the pipeline so that the valve flow
arrow appearing on the body casting is pointing in
the desired direction. Ensure that the valve is
positioned so that the cover can be easily removed
for future maintenance.
4. Ensure that the Control Trim is mounted properly
and all other components are positioned correctly
as per illustration.
5. After installation in the main line, carefully inspect/
correct any damaged accessories, piping, tubing, or
fittings. Ensure that there are no leaks.
6. Install the components comprising the Deluge Trim
Package in their proper positions in compliance with
all instructions, drawings, and technical
specifications describing the BERMAD Deluge
Valve, according to the relevant illustration.
7. All additional accessories, although not packed
together with the BERMAD Deluge Valve, must be
installed as shown in the relevant P&ID and other
illustrations.
Operation
Principle of Operation
The BERMAD FP 400E Deluge Valve (assembled with
specific trim) is suitable for systems that include
adequate detecting and piping systems with open
nozzles. The deluge valve prevents water from entering
system piping until required. The deluge valve is kept
closed by pressure applied to the control chamber
through a restricted priming line.
In the SET position, the water pressure supplied through
the priming line is trapped in the control chamber of the
deluge valve by a check valve, and by the normally
closed release device.
The pressure trapped in the control chamber of the
deluge valve presses the valve seal disc down, thereby
sealing the valve and keeping the system piping dry.
Under Test or Fire conditions, when the pressure is
released from the control chamber by the opening of the
automatic releasing device or by manual release, the
deluge valve opens and allows the inlet supply water to
flow through the valve and into the system piping and
alarm devices.
Warning: Whenever the handle of the Manual
Emergency Release is pulled, pressure is released from
the control chamber, the deluge valve will open, and
water will flow into system piping and alarm devices.

Valve Closed (Set Position)
Line pressure applied to the control chamber of the
valve creates a superior force that moves the valve to
the closed position and provides drip tight sealing.
Valve Open (Operating Conditions)
Releasing the pressure from the control chamber to
atmosphere or some other lower pressure zone causes
the line pressure acting on the seal disc to move the
valve to the open position.
