Emergency Vent Valve
Performance Driven
About the Product
The Fainger make Emergency Pressure Vents provide emergency pressure relief for storage tanks that are exposed to an external fire. They are designed to open and provide pressure relief beyond the capacity of the normal breather vents.
Hinged Emergency Vent is mounted on the tank manhole flange. Under emergency fire conditions, the cover can pivot open on its hinge and provide required relief, preventing damage to the tank due to excessive internal pressure. When tank pressure is reduced the cover automatically recloses. The hinged design allows the use of a lever principle counterweight so that the higher pressure setting can be given.
