Tank regulators BKRi2

(Low pressure reducing valve) 

Tank blanketing valves are commonly used in tank storage systems to prevent and protect against explosions (by preventing flammable liquids from venting from the vessel), to control product contamination against external air that can fill the vapour space, to reduce evaporation losses (hence production losses), to reduce internal corrosion (caused by air and moisture) and to prevent a vacuum condition. 

The blanketing process consists of covering the stored medium, usually a liquid, with a gas (usually N2). 

  • Compact design. 
  • Non-rising adjustment knob. 
  • FDA / USP Class VI compliant seals. 

STANDARD SURFACE FINISH 

  • Internal moving parts and machined surfaces: 
  • ≤ 0.76 micron Ra - SF3. 
  • Other surfaces: according to casting. 
  • Ultrasonic cleaning. 
  • Leakage line connection. 
  • Dome loading. 
  • Top cap (adjusting screw with cover). 
  • Pressure gauge connection on the body. 
  • External detection line connection (recommended for low set pressures < 10 mbar or high flow rates). 
  • Vacuum bleed. 
  • ATEX version.

  • Compressed air, nitrogen and other construction compatible gases. 

  • BKRi2 - low pressure regulator. 

  • 1/2" and 1"; DN 15 and DN 25. 

  • 5 to 10 mbar; 10 to 50 mbar; 20 to 200 mbar; 
  • 50 to 500 mbar; 5 to 4000 mbar (dome load). 

  • Flanged EN 1092-1 PN 16. 
  • Flanged ASME B16.5 Class 150.

  • Installation is recommended vertically, to allow for drainage, or horizontally as close to the process as possible to avoid long pipe runs and flow restrictions.
