Emergency Vent (Series 75)

In the event of a fire outside a storage tank, this instrument acts as a safety valve, relieving excess pressure inside the tank and canceling the possibility of explosion. It works when there is overpressure in the interior or a fire in the exterior. of the tank. The fire causes a rapid release of vapors that would normally lead to an explosion in the tank, but this is avoided thanks to the vent reducing the pressure of the vapors to a level that has been calculated in advance.
