Emergency Pressure Relief Vent (Weight Loaded)

Model No: 400

Storagetech’s Weight-loaded Emergency Relief Vent, model 400, operates as the last resort when a vessel or storage tank is exposed to large-scale fire, and the standard pressure relief valve has failed to open or cope with the extreme conditions.

A high rate of gas transfer occurs during a fire due to the increased evaporation rate, and these gases are released into the atmosphere via the emergency relief valve. The cover is manually placed back in place to guarantee tightness when the fire case would be resolved.

There is a choice of pressure release settings to enable a selection close to the maximum working pressure of the vessel.

The weight-loaded emergency pressure relief vent is installed in the horizontal plane on a flange at the top of the tank. A secondary use of the unit is to access the tank for product sampling or depth gauging.
