Belimo Energy Valve™ is an intelligent, pressure-independent control valve for HVAC applications. It is based on Belimo's characterised control valve (CCV) technology, which ensures tight closure. The flow through the valve is continuously measured by an ultrasonic flow meter. This meter includes a patented method for detecting and compensating glycol. Accurate flow information is used for electronic compensation of any pressure fluctuations in the system. 

The Energy Valve has integrated power control and delta T logic for performance monitoring and heat exchange optimisation by maintaining a minimum, freely adjustable differential temperature. In addition to the standard analogue signal and feedback, the Energy Valve communicates its data to the building management system (BMS) via Belimo MP-Bus, BACnet or Modbus communication. The integrated web server allows easy parameterisation of the Energy Valve and ensures clear visualisation of valve operation in real-time. Performance data is stored on the drive for 13 months. Belimo Cloud provides the option for lifetime data storage.

Certified Energy Measurement

Models of Belimo certified thermometers meet the requirements of EN1434 and have type approval in accordance with the European Measuring Instruments Directive 2014/32/EU (MID). This certification is mandatory in the Czech Republic if the meter data is used for billing purposes. They provide verified data for direct billing. Heat meters are approved according to MID for measuring heat in systems with clean water. Due to MID requirements, glycol must not be used in the system; if detected in the water, the device will issue a warning.

Energy Monitoring

The thermal energy supplied in the heating system is accurately measured and recorded using a reliable ultrasonic method. This data helps identify potential areas for optimising the HVAC system. When connected to the Belimo Cloud, it provides secure access to consumption data.

Glycol Measurement and Compensation

Glycol measurement and compensation ensure accurate energy measurement under all circumstances. An advanced, patented algorithm determines the percentage of glycol content in the fluid. This allows continuous monitoring during system operation. Additionally, energy measurement always occurs with accurate flow values.

Power Control

Power control redefines the control valve's regulation capabilities. This dynamic mode provides the only truly linear relationship between the control signal and output power. This control mode makes the Energy Valve independent of differential pressure and the temperature of the supplied water, ensuring greater comfort and minimising control oscillations.

Automatic Balancing

The volumetric flow through the valve is continuously measured, and pressure fluctuations in the hydraulic system are immediately compensated. This makes hydraulic balancing unnecessary.

Delta T Management

The integrated logic prevents the occurrence of low Delta T and ensures maximum comfort with the lowest possible energy consumption. Monitoring the correct delta T is important for performance monitoring and heat exchange optimisation.

Belimo Assistant App

Belimo Energy Valve™ is equipped with an NFC interface (Near Field Communication) allowing easy configuration and maintenance directly from a smartphone. Using the Belimo Assistant app, the device can be intuitively configured and values recorded during commissioning. Key performance indicators, which facilitate determining the device's "health status," ensure reliable operation. A range of diagnostic parameters shows how the device interacts with the system during operation. If maintenance is required, a fault analysis can be quickly performed.
