Breather Valves & Flame Arrestor
Direct acting Pressure/ Vacuum relief valves (Breather valve) is special designed for tank protection.
The range includes combined pressure vacuum valves, all available with Flanged outlets or vented to atmosphere, Pressure Relief valve with outlet or vented to atmosphere and Vacuum relief valve with Nitrogen purging flange or to atmosphere.
Pressure/vacuum relief valve are installed widely on storage tanks (fixed roof and floating Roof) to reduce vanishing loss. The valve stops the increase of excessive pressure or vacuum which can disturb the system or harm the storage vessel.
Storage tanks & other vessels containing flammable and explosive chemicals and mixture are prevalent in chemical process industries plants. Flame Arrester is installed on such equipment to prevent potential hazard associated with flammable and explosives materials. Flame Arrester can stop the spread of a fire, limit the spread of an explosive event, protect potentially explosive mixtures from igniting, and confine a fire within an enclosed, controlled location.
A flame arrester works by forcing a flame front through very narrow channels (MESG) has travels through the device, but the passages are so narrow that the flame can no longer be maintained.
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.
