Description
Energy Valve combines electronic PICV functionality with an integrated Energy Function, using supply and return temperature sensors to enable real-time thermal power control and energy monitoring. In addition to maintaining constant flow through high-resolution differential pressure sensors, the valve measures supply and return temperatures and calculates instantaneous thermal power based on the current ΔT and flow rate. This allows for precise thermal power regulation, ΔT optimization, and full energy monitoring via BACnet MSTP or Modbus RTU.
The Energy Valve range covers DN65–150, PN16, with flow capacities from 12 000 to 177 000 l/h, and supports media temperatures from –10°C to 120°C. It provides continuous monitoring of temperatures, flow, thermal power, energy consumption, alarms and diagnostic information.
Designed for heating groups, AHUs and high-capacity coils, the Energy Valve improves system efficiency by maintaining optimal ΔT, preventing coil saturation and enabling data-driven performance optimization.
