Model 4300
Spring Loaded Vacuum Vent End-of-Line
OBJECTIVE
The Model 4300 end-of-line spring
loaded vacuum vent is intended for use on storage tanks, vapor recovery systems
and process systems where higher vacuum relief settings are required.
TECHNIQUE
A spring loaded vacuum
pallet assembly in the vent housing remains closed until the set point is
reached during normal inbreathing due to product movement out of the tank
and/or temperature chances. When the set point of the vent is reached, the
spring loaded pallet opens to permit the intake of air to prevent tank damage.
Once the vacuum is satisfied the pallet closes providing a tight seal.
