The Energy Valve is a pressure independent valve that measures and manages coil energy by using an embedded electromagnetic or ultrasonic fl ow meter, along with supply and return water temperature sensors. The Energy Valve also has the patented Power Control and Belimo Delta T Manager™ logics built-in that monitors coil performance and optimizes the available energy of the coil by maintaining the Delta T. In addition to the standard analog signal and feedback wiring, it communicates its data to the Building Management System (BMS) via BACnet MS/TP or BACnet IP. The built-in web server collects up to 13 months of data that can be downloaded to external tools for further optimization. •Ultrasonic flow meter with temperature and glycol compensation is wet calibrated to obtain published accuracy specifi cations •Supply and return temperature sensors with thermowells and pipe fittings.
