Frese PV-SIGMA Compact

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.
