the cabinet and swings out 180 degree from left
to right. The cabinet comes with a standard springlock
and 6mm thick wire glass.The wordings on the glass
vary according to the fire protection systems in
which the breeching inlet is installed, eg., DRY
RISER INLET, WET RISER INLET, SPRINKLER BREECHING
INLET, FOAM INLET, etc., |
 |
The rear of the
cabinet panel has the cut-out holes for easy installation
of the breeching inlet to the pipework.
The quality of workmanship and its’ finishes
are carefully planned and executed from the initial
stage of preparing the material and fabricating
upto to the painting process.
The standard finishes of the electro-galvanised
steel and aluminium cabinets are “Red”
epoxy/polyester powder coated and oven baked.
Stainless steel cabinets come with 4B quality
finishes.
FEATURES:
- Compact and elegant design.
- Quality finishes in epoxy/polyester powder
coated and oven baked.
- Easy installation with pre-cut flange holes
at the rearpanel.

AUTO AIR RELEASE VALVE
“AE” automatic
ball float type air release valve is manufactured
from solid brass rods. The standard inlet connection
is male BSPT screw.
The air release valve is generally installed in
a Dry Riser System but it can also be used for wet
systems such as Wet Riser, Autormatic Sprinkler
and Fire Hosereel Systems.
The maximum hydraulic test pressure is 300 PSI and
recommended working pressure is 175 PSI. |
 |
OPERATION:
The automatic air release valve adopts
a simple 'ball float' operation using a renewable
hard rubber ball located at the upper valve chamber.
Air in the pipework is released through the vent
hole when it is initially charged up with water
until water reaches the ball chamber. The rubber
ball will be pushed upwards to the vent hole and
sealed it when the network of pipe is pressurized.
No maintenance is required but if any small debris
is trapped at the upper valve chamber, this can
be removed by opening the cap at the top. |

MATERIAL:
Brass but stainless steel 304 or 316 (for marine
and corrosive environment) are available upon
request only and subject to a minimum order quantity,
* 50mm air release valve is supplied on indent
basis and subject to a minimum order quantity. |

FLANGE INLET HYDRANT VALVES
“AE”
range of 65mm diameter “low-pressure”
globe pattern hydrant valves with flange inlet
connection comes in four different configurations
namely, “Oblique”, “Right-Angle”,
“Bib-Nose” and “Horizontal”
patterns.
The design and construction of the hydrant valves
are strictly in accordance with BS5041 : Part
1 : 1987 & generally to BS5154 : 1991 standards.
The valves are suitable for both on-shore and
off-shore fire protection applications.
The shut-off of the valve for good water-tight
sealing is done by using a high quality rubber
bonded seat disc which acts as a primary rubber
to metal seal, whilst a secondary metal to metal
shut-off is also incorporated in the design of
the valve.
Every hydrant valve manufactured is hydrostatically
tested to 16.5 bars and 22.5 bars for the valve
seat and body respectively. The internal casting
finishes of every valve is of high quality ensuring
a low flow restriction that meets the standard’s
water flow test requirement. The hydrant valve
comes complete with standard “black”

HIGH PRESSURE HYDRANT VALVE
“AE” Model
AE-PRV-1, 65mm diameter Gunmetal highpressure “Bib-Nose”
pattern regulating hydrant valve is field adjustable
which allows the user to set the valve outlet pressure
as desired according to the conditions of the fire
protection system in which the valves are installed.
The valve comes with screw (Fig.138) or flange (Fig.139FG)
inlet connections.
The design and construction of the hydrant valve
are strictly in accordance with BS5041 : Part 1
: 1987 and generally to BS5154 : 1991 standards.
It is suitable for connection to a high pressure
water supply of upto 21 bars (300 PSI) and provide
a constant reduced outlet pressure which can be
set in- situ during testing and commissioning of
the fire protection system.
This constant uniform set outlet pressure of the
valve, irrespective of its’ location in which
it is installed either in a high rise building or
off-shore plants safeguards the fireman from inconsistent
hose pressures in a fire situation. |
 |
The selection of the
materials in the manufacture of the valve are all
corrosion resistant, tough and durable. This ensures
the product long-life plus providing an efficient
service in the time of need. The shut-off of the
valve for good water-tight sealing is done by using
a high quality rubber bonded seat disc which acts
as a primary rubber to metal seal, whilst a secondary
metal to metal shut-off is also incorporated in
the design of the valve. Fig.138 Fig.139FG
Every hydrant valve manufactured is hydrostatically
tested to 22.5 bars and 30.0 bars for the valve
seat and body respectively. The valve outlet static
pressure is factory preset at 7.0 bars (100 PSI)
as required in the standard.
The internal casting finishes of every valve is
of high quality ensuring a low flow restriction
that meets the standard’s water flow test
requirement.
The hydrant valve comes complete with standard “black”
(“Red” is optional) plastic blankcap
and chain. Alternative blankcaps made of brass or
gunmetal are also available upon request. |
 |
OPERATION:
When the valve is open, the inlet pressure flows
into the upper part of the pressure chamber. By
adjusting the spring below, a balance pressure
of these two forces determines
the degree of the valve opening to maintain a
constant outlet pressure.
When the valve outlet pressure is regulated, it
will remain set unless it is being tempered. The
valve outlet pressure setting can only be regulated
under a “flowing” condition.
A small flow coming out of the valve outlet is
sufficient to perform the task.
The valve counter-balance spring design allows
the outlet pressure range to be regulated between
3.5 and 8 bars.
The inlet pressure ranges from 5.7 to 21 bars. |
