Intelligent Valve – 3-Port Control Valve with Integrated Energy Measurement

Description: The Intelligent Valve is a sophisticated 3-port control valve equipped with integrated energy data acquisition, catering to ventilation and air conditioning systems, as well as precontrol circuits within HVAC applications. Featuring sensor-guided dynamic flow control, it seamlessly integrates into building control technology via BACnet IP and Modbus RTU protocols. Additionally, it facilitates direct data transfer to Siemens Building Operator, enhancing system management capabilities.

Features:

  • Integrated energy data acquisition
  • Sensor-guided dynamic flow control
  • Compatible with BACnet IP and Modbus RTU for system integration
  • Direct transfer support to Siemens Building Operator
  • Ultrasonic volume flow measurement with ±2% accuracy for water and ±6% for water-ethylene glycol mixtures
  • Temperature measurement facilitated by paired immersion temperature sensors
  • Analog (DC 0/2...10 V or 4...20 mA) or digital integration options
  • Local limitation and optimization functions for energy-efficient operation
  • Three control functions: Dynamic control valve, Dynamic control valve (changeover), Flow temperature controller, Outside temperature-dependent flow temperature controller

Use: The Intelligent Valve (EXG.. and EXF.. models) serves as a versatile solution for heating, ventilation, and air conditioning systems, offering volume flow, temperature, and power measurement capabilities. It seamlessly integrates into temperature control circuits either as analog or digital components. Even when integrated as analog, all process data remains digitally accessible. Its local limitation and optimization features contribute to energy-efficient system operation. Integration with the Siemens Building Operator app enables remote system operation, monitoring, and energy consumption evaluation.

This Intelligent Valve model offers three distinct control functions, ensuring adaptability to various system requirements and operational scenarios.
