Model 3400
Pressure Only Vent To Atmosphere
OBJECTIVE
The Model 3400 pressure vents are
designed vent is designed for use on atmospheric and low-pressure storage tanks
where pressure relief is required.
TECHNIQUE
Under normal operating
conditions, the pallet assembly is closed providing a vapor-tight seal. In the
event the tank pressure increases to the set point of the Model 3400, the
pallet lifts to vent excess vapors thereby protecting tank from dangerous
over-pressurization. Pallet automatically closes and reseals when the pressure
is reduced.
