Spring Loaded Pressure / Vacuum Vent
The Model 4200 Spring Loaded Vent
provides pressure and vacuum relief in applications where higher pressure
settings are required and that require vapors to be piped away.
A spring loaded pallet on the
pressure side of the vent allows the discharge of vapors to the outlet piping
when the tank pressure exceeds the set point and a weight loaded /spring pallet
on the vacuum side of the vent allows the intake of air when the tank vacuum
exceeds the set point.
The pallets open and close to
regulate the tank pressure within permissible limits to avoid damage to the
tank as the tank normally breathes due to the thermal changes or product
movement. Virtually eliminates the intake of air and the escape of vapors,
except during normal tank breathing, thus reducing product loss
