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.

Applications

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

Typical application:

  • Radiator systems

Features

  • Size range from DN15 to DN50
  • Max. flow 10.3m3/h
  • Max. differential pressure 400kPa
  • Setting ranges: 5kPa-30kPa, 20-60kPa and 20-80kPa
  • Differential pressure regulation, flow regulation, drain and PT plugs as standard
  • Isolation function on the SIGMA Compact
  • Compact housings for easy installation

Key benefits

  • Simple pre-setting of flow and differential pressure
  • Flow and differential pressure can be adjusted independently
  • Differential pressure can be easily adjusted after installation
  • Tamperproof pre-setting 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
