Breather Valve |
|
| |
A Breather Valve is a safety feature attached to a nozzle opening on top of storage tank with a fixed roof. The valve is one type of relief valve and its main function is to provide sufficient air to the storage tank when the tank is in an out-breathing condition |

Breather valves are low pressure device designed to protect tanks, recess systems and equipment from damage due to over pressure or vacuum. They are also know as pressure/vacuum relief valves. Breather valves retain toxic vapours thus preventing atmospheric contamination and increased fire protection and safety. Retention of vapour also minimizes production losses through evaporation.
Pressure/Vacuum relief valves are used extensively on bulk storage tanks, including fixed roof tanks with floating cover, to minimize evaporation loss. The valves prevent the build up of excessive pressure or vacuum that can damage the storage vessel. Pressure and vacuum protection levels are controlled with weighted pallets or spring and can be combined to provide the required pressure/vacuum setting. |

| Emergency Relief VALVES |
Emergency Relief Valves are fitted to storage tanks to allow emergency flow due to the excessive venting requirement from a fire burning around a storage tank. This eliminates a costly tank rupture, providing emergency venting from abnormal internal pressure beyond the capability of the pressure relief vent. In the event of a fire, the pallet will lift at a pre-determined pressure, thus creating a large venting area.
A PTFE/EPDM insert is provided to achieve leak tight sealing between the pallet and seat under normal operating conditions. An alternative model is available, fitted with an additional spring-loaded vacuum valve that will open under negative pressure to protect the tank from any damage that may occur under vacuum conditions.
