Pressure and vacuum relief
breather valve is designed to protect low pressure storage tanks
from excessive pressure (or vacuum) created by thermal expansion
(and contraction) and product movement into(out of) the tank
and at the same time minimizing costly product evaporation/loss.
Excesses in pressure or vacuum may also cause permanent deformation
to the tank or unbalance a vapor recovery system.
The pressure and vacuum relief breather valve is installed
on the storage tank roof. The valve may be mounted in conjunction
with a KSFH or KSFI flame arrester to provide maximum protection
against excessive pressure and vacuum while minimizing accidental
ignition of flammable product vapor from external sources

According to API 2000 code, the pressure &
vacuum relief valve of Model KSBB and KSBS are designed,
manufactured and tested.
Model KSBB, which is used for the protector of fluid storage
tank, is composed of one body with the functions of pressure
relief and vacuum relief. (Model KSBS is used
for the pressure setting above 1 PSIG)
This valve has function to intake the air under constant
pressure during unloading, and to discharge the overpressure
generated during pouring the fluid into storage tank.
This is the safe valve to control the deflation(vacuum)
and inflation(pressure) of several storage tanks. |

| According to API 2000 code, the pressure relief
valve with pipe away type of Model KSBD and KSDS are designed,manufactured
and tested.
Model KSBD and KSDS, which is used for the protector
of fluid storage tank, is composed of pressure relief
function.(Model KSDS is used for pressure setting above
1 PSIG)
The vent valve should be the pipe away type for the
condition of driving pressure and the retreatment of
poisonous and flammable gas and steam. For this reason,
TANK TECH has produced the Model KSBD and KSDS.

| According to API 2000 code, the pressure &
vacuum relief valve with pipe away type of Model KSBG
and KSGS are designed, manufactured and tested.
Model KSBG and KSGS, which is used for the protector
of fluid storage tank, is composed of a body with the
function of pressure relief and vacuum relief.
(Model KSGS is used for the pressure setting above 1
PSIG)
In case of using the vapor recovery system of combustion
poisonous and flammable gases in the storage tank at
the flare stack, our KSBG and KSGS Models can be used
to pipe away type

| According to API 2000 code, the pressure &
vacuum relief valve with steam traced of Model KSBJ and
KSJS are designed, manufactured and tested.
Model KSBJ and KSJS, which is used for the protector
of fluid storage tank, is composed of a body with the
functions of pressure relief and vacuum relief.(Model
KSJS is used for the pressure setting above 1 PSIG)
Some special fluids or gases are sublimated at room
temperature. The safety of tank is kept by the supply
of external heat and the normal operation of valve disc
for venting. Model KSBJ and KSJS type are designed
and manufactured to supply the steam through the steam
traced of the main valve.

valve of Model KSPR and KSPS are designed, manufactured
and tested.
Model KSPR and KSPS, which is used for the protector
of fluid storage tank, is composed of pressure relief
function.(Model KSPS is used for pressure setting above
1 PSIG)
For the inflammable gases, blanketing system is used
to supply the inert gas into the tank and to suppress
the oxygen supply into the tank during the vacuum phenomena.
For the overpressurizing inside of the tank.Model KSPR
and KSPS is designed to discharge it through the pressure
relief valve

valve of Model KSVR and KSVS are designed, manufactured
and tested.
Model KSVR and KSVS, which is used for the protector
of fluid storage tank, is composed of vacuum relief
function. (Model KSVS is used for vacuum setting above
1 PSIG)
Under the only depressuring condition inside of the
tank like silo, Model KSVR type is designed to be added
only vacuum relief valve.
