Description

DESCRIPTION
Tank blanketing valves are commonly used in tank
storage systems to prevent and protect against
explosions (avoiding flammable liquids being vented
from vessel), to control product contamination against
external air that may fill the vapour space, to reduce
evaporation losses (consequently product losses), to
reduce internal corrosion (caused by air and moisture) and to prevent vacuum condition.
The blanketing process consist in covering the stored
medium , usually a liquid, with a gas (normally N2).

MAIN FEATURES
Compact design.
Completely machined from barstock material, no
castings or forgings are used on the standard version.
No rising stem

STANDARD SURFACE FINISH
Internal wetted parts: ≤ 0,5 micron Ra
External : ≤ 0,8 micron Ra
( 0,25 micron Ra and electro polished as option)
Ultrasonic cleaning

OPTIONS:
Leakage line connection 1/8” (captured vent)
Gauge connection on body
External pulse lines (recommended for low set
pressures < 10 mbar or high flow)
Dome loaded (for higher pressure control)
Angle connection design
Blanketing with vacuum

USE: Compressed air, nitrogen and other gases
compatible with the construction.

AVAILABLE MODELS: BKR – Low pressure regulator

SIZES: DN 1” – DN25

OUTLET SPRING RANGES: 5 to 500 mbar (4000mbar with dome load)

CONNECTIONS: Clamp ends or others on request

PACKAGING:
Assembling and packaging in a clean room
certified according to ISO 14644-1.
The product is end capped and vacuum sealed
with recyclable plastic film to avoid
contamination.

INSTALLATION:
Vertical installation recommended (to allow
draining) or horizontal as close to process as
possible in order to prevent long pipe sections
and flow restrictions.
For an economical consumption of blanketing
gas the pressure must be adjusted to remain
slightly above the atmospheric pressure, while
filling and empting the vessel. See IMI.

ORDER REQUIREMENTS:
Type of fluid
Maximum operating temperature
Inlet pressure and required outlet pressure
Capacity (maximum and minimum).
