The IBF range of Double Block and Bleed Valves meets the requirements of the process industry, in a particular, natural gas and aggressive media applications.

The compact design of the IBF range integrates one or two shut-off valves, this allows the process to be separated from the instrument side and vent valve. The modular design allows the arrangement of ball valves and/or needle valves to be used, ball valves are recommended for applications with liquid media or dirty processes due to easy cleaning of the straight-through internal bore.

The seat design and the redundant seals of the valve body ensure high durability and tightness.

If the soft seal fails, the metal-to-metal seat will ensure that the valve can still be operated and set to a safe position. The tightness is guaranteed for the connection between the process and the measuring instrument and out to atmosphere.

The superior machined finish of the internal parts allows very smooth and precise operation, even at high pressures or after long periods without valve operation. The surface finish also minimises corrosion with aggressive media and allows easier maintenance.



  • Oil and gas industry, chemical and petrochemical industries, power plants and general process industries
  • Liquids and gases, including aggressive viscous or crystallising media
  • Direct connection of pressure measuring instruments to flanged pipes or vessels without the need for additional interface valves
