Prssure / Vacuum Relief Valve(MODEL:NK-BV12 Series)
Pressure / 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 pressure/vacuum relief under normal pump in/out and thermal breathing conditions.
: As the pressure in the storage tank increases, the vacuum pallet is held shut.
When the set pressure is reached, the pressure pallet lifts and relieves to atmosphere (or to a header if it a pipe away valve).
: As a vacuum is drawn in the storage tank (for example, when fluid is being pumped out),
the pressure pallet is held shut by atmospheric pressure. When the vacuum setting is
reached, the pallet lifts and air is drawn in the storage tank from the atmosphere.
Model NK-BV12 is designed to protect the low-pressure tank from damage created by overpressure or excessive vacuum.
Model NK-BV12, has a self draining house and drip ring to protect the seating
surfaces from condensation and freezing. The pressure and vacuum relief valve is
installed on the storage tank roof. Also can this valve be mounted in conjunction with a
NK-FA21T flame arrester to protect against ignition of flammable vapors from external
sources as well as to provide pressure vacuum relief.
Model NK-BV15 is used for pressure and vacuum relief where vapors must be piped away.
