 产品介绍

The SKP50... controls the differential pressure in the gas supply line in function of the differential pressure in the supply air duct.

The air / gas volume ratio thus remains constant regardless of air volume changes.

The SKP50... also provides the functions of a safety shutoff valve to EN 161 when used in connection with Landis & Staefa gas valves type VG...

Control of the air / gas volume ratio on multi-stage or modulating gas burners with a central or decentral air supply.

Major fields of use:

  • In burner plants with integrated heat recovery systems

  • On burners with an adjustable air / gas mixing facility in the burner head

  • In plants where, in the case of load changes, the pressure conditions in the burner and in the combustion chamber do not change in a linear fashion

  • In plants with negative pressures on the gas or air side

With the SKP50... - in contrast to conventional compound control - air volume variations caused by

  • mains voltage fluctuations

  • dirty fan wheels

  • changes in the combustion chamber pressure

  • associated heat recovery systems

have no impact on the quality of the combustion process.

When using the SKP50..., a separate gas pressure governor is not required. Since the integrated gas pressure controller does not cause any additional pressure losses, a smaller valve size than usual can be chosen on most applications. The usual measures required for ensuring the minimum air volume must also be taken when using the SKP50....
