Product Description

The V5005T Kombi-FCU is a Pressure Independent Control Valve (PICV). It combines a flow controller and a full stroke, full authority temperature controller in one valve. Equipped with an actuator Kombi-FCU provides a full stroke modulating temperature control. It is suitable for use in variable and constant flow systems. They may be used as constant flow limiter in constant flow systems (without an actuator) or as a Pressure Independent Control Valve in variable flow systems.

V5005T Kombi-FCU is typically used for balancing and temperature control of fan coil units, chilled ceilings and one-pipe heating systems.

  • Automatic pressure independent balancing and control
  • Precise pressure independent flow performance
  • Highest energy saving potential due to efficient energy transfer and minimized pump speed
  • Measuring possibility to find the optimal setpoint for the pump
  • Versions with or without measuring connections available
  • Reduced movements of actuators as pressure fluctuations do not influence the required temperature
  • No complex calculation needed for selection
  • No balancing method needed for commissioning
  • Wide range of application
  • Sizes DN15 to DN25 cover all popular sizes on FCUs
  • Various versions to support standard flow rates as well as low flow and high flow needs
  • Covers hydronic balancing and temperature control in one valve thus reducing mounting costs
  • Easy commissioning
  • Presetting with visual flow scale indicating directly the preset liters per hour
  • Pre-setting by hand without the need of tools
  • Can balance a system even if only parts of a building are in operation
  • Maintenance friendly
  • Emergency shutoff function with plastic cap - not for permanent use
  • Measuring possibility for problematic applications (only with versions having measuring connections)
  • Dirt resistant no dead zones in the valves. Continuous flow assures self cleaning effects
