INTRODUCTION

Vacuum relief valves are used on liquid storage tanks and other process vessels or systems to
prevent structural damage due to excess internal vacuum.
Storage tanks are pressurized when liquid is pumped in, compressing the existing vapor or
when rising temperatures cause increased evaporation or expansion of existing vapor.
Conversely, a vacuum condition may be created when pumping out or due to falling
temperature. To prevent tank damage, vapor must be allowed into or out of the tank at
specified vacuum condition. The volume rate of venting depends upon the tank size,
volatility of the tank contents, the pumping rates and the temperature.

DESIGN AND FUNCTION

Tank protection equipment typically includes an operating valve, which is designed to
provide vacuum relief under normal pump out and thermal breathing conditions.

Vacuum Relief
: As a vacuum is drawn in the storage tank (for example, when fluid is being pumped out).
When the vacuum setting is reached, the pallet lifts and air is drawn in the storage tank
from the atmosphere.
