PV-SIGMA Compact

Dynamic Pressure and Flow Regulation

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

The 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 PV Compact differential pressure control valve positioned in the return.

The 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 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
