Emergency Relief Vents for Storage Tanks

Product Description

Emergency Relief Vents

Emergency Relief Vents 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 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.
