Emergency Vent

Emergency Vent acts as a secondary relief device providing an extra layer of protection in case the breather valve installed on the storage is not capable of relieving the sudden rise in pressure.

Abnormal conditions generated due to heat or fire exposure may create excess internal pressure and a valve sized to handle normal venting requirement may fail to work under such conditions. Kingsley dead weight loaded emergency vent ensure protection of storage tanks against excess internal pressure.

Specification
