The Intelligent Valve is a 2-port pressure-independent control valve (PICV) with volume flow, temperature and power measurement for heating, ventilation, and air conditioning plants.
The valve can be integrated as analog (DC 0/2...10 V or 4...20 mA) or digital (BACnet IP) into the temperature control circuit. All process data (volume flow, power, primary flow and return temperature, etc.) can still be read out digitally even if integrated as analog.
The Intelligent Valve also has local limitation and optimization functions that support energyefficient plant operation. In addition to digital integration in the building automation and control system, integration in the cloud with the Siemens Building Operator app supports the building operator to operate and monitor the system as well as evaluate energy consumption.
The Intelligent Valve 4 control functions:
● Dynamic control valve
● Differential pressure controller
● Flow temperature controller
● Outside temperature-dependent flow temperature controller Volume flow limitation and energy acquisition are available at any time in all 4 control functions.
Intelligent Valve as dynamic control valve In this control function, the Intelligent Valve is part of a temperature control circuit and receives a setpoint from a superposed automation station that it interprets, depending on the control mode, as valve position, volume flow, or output and controls accordingly.
The example to the right depicts this based on a precontrol circuit for chilled ceilings.
Automation station [N1] controls the flow temperature of the chilled ceiling circuit by demand and specifies the setpoint of 0…100 % on the Intelligent Valve. This can occur in analog (0…100 % = DC 0…10 V) form or remotely over BACnet IP.
The Intelligent Valve follows this setpoint and sets, for example in volume flow control mode, the appropriate volume flow
