The Model 4500 spring loaded pressure vent with pipeaway is intended for use where higher set pressures are required and the relieving vapors must be piped away and not emitted into the atmosphere. May also be used for in-line vacuum relief.


A spring loaded pallet allows for the discharge of vapors to the outlet piping when the tank pressure exceeds the pressure set point. Once the tank over pressure is relieved the spring loaded pallet closes providing a tight vapor seal. A flanged outlet connection is provided for easy pipe-away of vapors, eliminating their emission into the atmosphere and allowing compliance with applicable regulations.
