Knolval™ Energy Valve PN25

Knolval™ is an intelligent energy valve integrated into the Building Management Syste(BMS) dedicated to climate control.

Thanks to the support of Niagara technology, it turns valves into active, intelligent nodes that precisely control the amount of fluid flowing through the system’s branches and terminals.

Through the Niagara platform, Knolval™ interacts with other system components such as environmental sensors, circulators and generators (boilers, heat pumps and chillers); it manages the correct amount of thermal energy in each area controlled by the valves; it optimises the overall thermal and electrical consumption.

With EasyLink and EnergyLink, Knolval offers a range of precise and tangible benefits, such as:

  • Account for heat and cooling energy.
  • Make the most of existing installations (retrofit).
  • Improve room conditions and people’s comfort.
  • Reduce emissions and consumption.
  • Identify unknown waste and ‘invisible and silent’ malfunctions.
  • Programme the optimal operation of installations, monitoring their continuity.

Main Features

  • Available sizes: ½’’, ¾’’, 1’’, 1’’1/4, 1’’1/2, 2’’
  • PN25
  • Temperature range: -10°C to 110°C
  • Measurement and control of flow rate, temperature, and power
  • Integrated electronic board for measurement, control, and communication
  • Energy meter for heating and cooling applications
  • Flow totalizer
  • Designed for integration with Building Management Systems (BMS)
  • RGB LED for operational status indication

Control Strategies

Knolval enables the implementation of the following control strategies:

  • Flow rate control (Q)
  • Return temperature control (Tr)
  • ΔT control (Tm-Tr)
  • Valve opening degree control (%)
  • Control strategy based on an external sensor signal (Temperature, Relative Pressure, Differential Pressure)
  • Local or remote external enabling (protocol)

BENEFITS

  • If you already have a BMS, KnolvalTM pairs with it and does not force you to change it.
  • KnolvalTM lives and operates on Google Cloud, therefore your company avoids worrying about server, software, updating, antivirus… You just benefit from a much greater IT security than a single company server.
  • Knolval™ adapts to a wide range of applications and systems, automatically adjusting to operating conditions thanks to the optimization logic implemented on Niagara.
