Belimo's Energy Valve is a two-way pressure independent control valve designed for building owners who want to continuously control and monitor energy usage and develop energy savings strategies through their BAS.
Belimo's Energy Valve is a pressure independent valve that optimises, documents and improves water coil performance.
The Energy Valve is a two-way pressure independent valve using the Electronic Pressure Independent Valve (ePIV) platform that measures the coil energy using an embedded electromagnetic flow sensor, water supply and return temperature sensors.
The Energy Valve uses the Belimo Delta T Manager algorithm, which monitors the coil performance and optimises the available energy of the coil.
It has a standard analogue signal and feedback wiring and communicates data to the DDC system via BACnet MS/TP, BACnet IP and TCP/IP.
The actuator stores all the coil performance data such as Delta T (temperature difference) and energy usage.
All of the coil performance data, stored trends and control functions can be sent to the BAS via the data network.
The Energy Valve not only keeps owners and operators informed of coil performance, but the built-in Belimo Delta T Manager helps operators analyse and fine tune performance under any and all conditions.
Once these problems are eliminated, the opportunities for system wide optimisation open up.
At that point, owners, engineers and contractors can realise a host of benefits from the Belimo Energy Valve, including:
Combat low Delta T: the risk of low
Delta T (the most common culprit of major system inefficiencies) is dramatically reduced or eliminated
Enhanced energy optimisation: owners capitalise on optimisation strategies such as variable flow pumping without risking occupant comfort
Improved commissioning: start-up commissioning as well as retro-commissioning is greatly simplified
Better system maintenance: operators are much more informed about coil performance and thus better able to schedule preventive maintenance measures
Green certifications: the Belimo Energy Valve’s ability to analyse, document and optimise performance data to the BAS contributes toward satisfying credit EAc5: Measurement and Verification under LEED
More effective control: engineers are able to implement more advanced control strategies by taking advantage of the data logging provided at individual coils
Smaller equipment: buildings are able to meet comfort demand with smaller, less expensive piping and equipment.
