BREECHING INLET CABINET

“AE” range of 2-way (Fig.200 and Fig.210) and 4-way (Fig.220 and Fig.230) breeching inlet cabinets are generally fabricated from electro-galvanised steel material. Aluminium or stainless steel materials are available upon request.
The breeching inlet cabinets are manufactured strictly in accordance with BS 5041 : Part 5 : 1974.
The door hinges are either riveted or welded to 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.

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” (“Red” is optional) plastic blankcap and chain. Alternative blankcaps
made of brass or gunmetal are also available upon request.

FEATURES:

  • Compact and elegant design with excellent flow characteristics.
  • High quality casting finishes.
  • Primary shut-off by rubber to metal and a secondary metal to metal seating.
  • Corrosion resistant and quality materials used for durability, long-life and efficiency.
  • Maintenance free.
CONNECTIONS:

65mm dia BS4504 PN16 flat-face flange.
65mm BS336 female instantaneous.
Optional inlet flange to BS10 Table D or E flange, ANSI #150 are available upon request.

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.


FEATURES:

  • Compact and elegant design with excellent flow characteristics.
  • High quality casting finishes.
  • Primary shut-off by rubber to metal and a secondary
    metal to metal seating.
  • Corrosion resistant and quality materials used for durability, long-life and efficiency.
  • Maintenance free.
