Model 3600
Side-Mounted Vacuum Relief Vent
OBJECTIVE
The Model 3600 vacuum relief
vents are intended for use on atmospheric and low pressure tanks, vapor
recovery systems and process systems where vacuum relief is required. Built for
dependable service and superior seat tightness, these durable vents are
designed to be mounted to the tank structure or
process piping.
TECHNIQUE
The weight 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 pallet closes.
The model 3600 virtually
eliminates the intake of air except during normal tank in breathing.
