Model 4500
Spring Loaded Pressure Vent with Pipe-Away
OBJECTIVE
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.
TECHNIQUE
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.
