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.
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:
DN15 to DN50
Housing: DZR brass, CW602N (DN15-32), ductile iron (DN40-50)
Flow setting: PA6 (20% glass)
Spring: stainless steel
