Frese PV-SIGMA Compact

Dynamic Pressure and Flow Regulation

The Frese PV-SIGMA Compact system is a dynamic valve arrangement designed to regulate flow and differential pressure.

The Frese PV-SIGMA Compact system can be installed in both domestic and commercial heating and cooling systems.

The PV-SIGMA Compact combines the Frese SIGMA Compact dynamic balancing valve positioned in the flow and the Frese PV Compact differential pressure control valve positioned in the return.

The Frese PV-SIGMA Compact system ensures 100% flow and differential pressure regulation under all conditions, irrespective of any changes within the system whilst providing simple and trouble free commissioning.

The Frese PV-SIGMA Compact system operates by limiting the flow and pressure in a system, eliminating any noise caused by excess differential pressure.

Benefits

Simple presetting of flow and differential pressure
Flow and differential pressure can be adjusted independently of each other
Differential pressure can be easily adjusted after installation
Tamperproof presetting device fitted on the top of the differential pressure control valve
No additional commissioning required if the system design is changed
High levels of comfort and energy savings for the end user
The PV Compact eliminates noise caused by high differential pressure whilst the SIGMA Compact limits the flow in a system, ensuring no overflows
