A two-way pressure independent control valve, the Belimo Energy Valve™ optimizes, documents, and proves water coil performance. It uses the Delta T Manager™ algorithm to directly control coil performance. It also monitors the coil performance characteristic curve and resulting energy/power output. The valve has standard analog signal and feedback wiring and communicates data to the DDC system via BACnet MS/TP, BACnet IP, and TCP/IP for building automation system integration. Data logging and trending are integrated in the valve actuator or data can be captured using the BAS. The valve is designed for building owners who want to continuously control and monitor energy usage, and develop energy savings strategies through their BAS. The product range consists of 2½- to 6-inch valve body sizes.
