Use Intelligent Valves EXG.. and EXF.. are 3-port valves 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/ Modbus RTU) 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.
Intelligent Valve as flow temperature controller without outside air temperature sensor In this control function, the Intelligent Valve assumes the role of the automation station. Using an auxiliary secondary flow temperature sensor [X3], it acquires the flow temperature and controls to the present temperature setpoint by adjusting the volume flow for port A and B. Possible sensor types at [X3] are passive sensors with sensing elements LG-Ni-1000, DIN-Ni-1000 or Pt1000 (385/EU).
Technical design Basic design The Intelligent Valve combines four main functions: ● Exact, continuous volume flow measurement with an ultrasonic flow sensor ● Precise temperature measurement using paired Pt1000 temperature sensors ● Precise volume control using a control valve with a high-resolution actuator ● Dynamic hydraulic balancing, power and energy calculations, storage of cumulated flow and energy data as well as network integration via a central control unit EXG4U10E.. 1 EXF4U20E..
Position control The control valve position is proportional to the setpoint (setpoint 0 % = closed; setpoint 100 % = H100) – whereby the limitation to the applicable maximum volume flow (V̇100 or V̇max) remains active. Dynamic volume flow control is inactive in position control mode. There is no electronic modification to the kVS valve characteristic.
Volume flow maximum limitation We recommend activating the volume flow maximum limitation if the design volume flow for the partial plant (heating coil/cooler/precontrol circuit) as controlled by the Intelligent Valve, is lower than the nominal flow of the Intelligent Valve. In volume flow control mode, the set volume flow V̇max – which can be anywhere between 30...100 % of the nominal volume flow – is interpreted as the 100 % setpoint. It only serves as the limitation value in the other control modes.
Not all limitations are available to each control mode.

We recommend installing a filter or strainer, e.g. ALX.., in the flow to the heat exchanger. This increases the reliability and life cycle of the Intelligent Valve. The flow sensor and control valve can be installed separately: Threaded versions: In general, note that the torque of the threading is very high (75...500 Nm).
Mounting The Intelligent Valve is assembled at the mounting location. No adjustments, with the exception of configuring with the ABT Go app (see Commissioning [➙ 20]) nor special tools are required. Separate mounting instructions are included with the valve and flow sensor. Mounting positions 90° 90° Mount the flow sensor in the return if the media temperatures exceed (>90 °C). If not possible, mount the Intelligent Valve controller remotely from the flow sensor and use the wall-mount plate EZU-WA.
As an alternative, the sensors can be immersed directly in off-the-shelf ball valves with integrated measuring points (e.g. Siemens WZT-K.. / Jumo 902442/11) or t-pieces (e.g. Jumo 902442/31). The brass protective pockets EZT-M40 are available for mounting with protective pockets. Flanged valves EXF4U20E.. The EXF.. flanged valves include the temperature sensors EZU10-10025 for installing in the protective pockets EZT-S100 (also included). Welding sleeves must be planned on the construction side (e.g.
Commissioning The device has only a simple user interface. Siemens ABT Go app is used to actually commission the device. ABT Go App (Version 3.3.1 or later) The Siemens ABT Go app is available in iOS and Android versions in the corresponding app stores and can be used on smartphones and tablets. It connects directly over WLAN. The Intelligent Valve's own WLAN button activates the device's WLAN access point.

Network integration Modbus RTU The Intelligent Valve can be integrated over EIA-485 in a Modbus RTU network. Although the RS485 standard is simple and well-proven, important requirements and experience must be taken into account. This starts with the selection of the topology: ● Best: Individual line – The best topology is a single line (line topology)m with the bus cable connected directly tot he individual devices (daisy chain). This type of connection has the fewest problems.
