BREATHER VALVE WITH FLAME ARRESTOR
Breather Valve with Flame Arrestor is a tank protection device, which safeguards tank/ vessel from over pressurization or fire. This is a combination of Pressure Vacuum Relief Valve with in-built Flame Arrestor.
These are generally, dead weight type for standard set pressures. If required, these can be given as spring loaded for higher set pressures.
Flame Arrestor is designed to control transmission of flame in container with the help of arrestor element. The element quenches flame by absorbing and dissipating its heat to below the flash point. The arrestor dispenses and cools an approaching flame to a temperature below the vapor’s ignition point thus protecting the unprotected side of the device.
This Pressure Vacuum Relief Valve with built- in Flame Arrestor is a compact unit and less in weight. Being less in weight and friendly for cleaning of flame arrestor element and maintenance of pallets, these are preferred over the conventional separate in-line Flame Arrestor and Breather Valve combination.
These are designed specifically to provide separate flame arrestor elements for both pressure relief as well as vacuum relief port.
Flame Arrestors:
A flame arrestor is used to prevent the propogation & transmission of flame generated in the line from an unprotected side to the protected side of a flame arrestor but at the same time to allow the vapours to pass to the protected side. Flame Arrestors are installed on the vents of storage tanks and vessels or in process lines where flammable gases are being transferred.
We manufacture our Flame Arrestors according to IS:11006 & International Electro Technical Commission code IEC 60079-1:2007. Prototype tests according to mentioned codes for IIA, IIB & IIC gas groups have been conducted at Central Institute of Mining and Fuel Research (CIMFR), Dhanbad.
There are two types of Flame Arrestors:
1) End of Line type - Used for above ground storage tanks
2) In-Line Type - Used for underground storage tanks and in continuous process lines.
We also provide the customer with assistance in sizing and selection of Flame Arrestors according to API 2000 .
