The Frese Sigma dynamic balancing valves is used for water control in the HVAC industries.

The externally adjustable valve provides simple and accurate flow limitation and isolation. The internal differential pressure control function ensures that the set flow rate is limited irrespective of fluctuations in the differential pressure of the system. SIGMA Compact can isolate up to 10bar differential pressure.

Applications

The Frese SIGMA Compact can be used in both heating and cooling systems for the effective distribution of flow in various sections of the system. It can be used instead of traditional double regulating valves and can be installed in both variable flow systems and constant flow systems.

Typical applications include:

  • Fan coil units
  • Chilled beams
  • Radiator circuits
  • Underfloor heating circuits
  • Injection circuits

Key benefits

  • Easy to size and select as only the flow rate is required
  • Simplified system design with the number of balancing valves being reduced
  • Works as a flow limiter ensuring no overflows
  • Easy to install and adjust on site
  • Provides flexibility if the system is modified after the initial installation
  • Simplifies the commissioning process and reduces commissioning time due to automatic balancing of the system
  • High level comfort for the end-users as a result of the correct balance of the hydraulic system
  • Reliable operation as a dynamic balancing valve automatically finds the hydraulic balance regardless of pressure fluctuations in the system
  • Reduces the number of valves to install as no main circuit or branch balancing valves needed in the system

Key features

  • Removable differential pressure cartridge solution simplifies flushing procedure
  • No minimum straight pipe lengths required before or after the valve
  • Built-in optional P/T ports for needle system
  • Easy adjustment of the flow by the lockable handle
