Technical data for Belimo Energy Valve 272031 and 272046, including flow control, temperature measurement, power supply, and installation notes.
The Belimo Energy Valve 272031 and 272046 are energy metering, pressure-independent control valves for water-side HVAC applications. They measure flow and temperature using built-in sensors and control power via Power Control logic to optimize performance regardless of pressure or temperature variations. The valves support communication protocols including BACnet IP, BACnet MS/TP, Modbus RTU/IP, and web server access. They are designed for chilled or hot water systems with up to 60% glycol, and feature stainless steel ball and stem, nickel-plated brass body, and EPDM packing. Installation includes wiring diagrams and safety warnings for live electrical components.
