Model 4600
Spring-Loaded Side-Mounted Vacuum Relief Vent
OBJECTIVE
The Model 4600 spring-loaded
vacuum relief vents are intended for use on low pressure tanks, vapor recovery
systems and process systems where higher vacuum relief is required.
TECHNIQUE
The spring-loaded pallet in the
vent housing allows the intake of air necessary to maintain the tank pressure
within the permissible vacuum limit to avoid damage to the tank.
Once the vacuum condition is
satisfied and the pressure is within the permissible limits the spring-loaded
pallet closes. The Model 4600 virtually eliminates the intake of air except
during normal tank in breathing.
