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.
