About this file
This is a Brand Name or Equal Worksheet documenting the salient characteristics for the Armstrong DRV80 Digital Recirculation Valve. The document establishes the essential technical specifications that equivalent products must meet to satisfy Government requirements under VAAR 811.104 and 811.105.
The Armstrong DRV80 is a stainless steel digital recirculation valve with 3" NPT female inlet and outlet connections, rated for indoor use with NEMA 3S and IPX4 protection. Key operational parameters include inlet supply pressures between 20-200 psi, hot water temperatures up to 185°F, minimum cold water supply temperature of 35.6°F, and minimum continuous recirculation flow of 10 GPM. The valve features seven fail-safe cold triggers with integral self-diagnostics, programmable over-temperature limits, and a configurable set point range of 81°F to 158°F. Electrical requirements specify 120-240V AC at 50/60 Hz with grounding, dual 6V CR-P2 batteries, and ambient operating conditions of 35°F to 122°F with 95% non-condensing humidity. The device includes multiple connectivity options: onboard Bluetooth with SAGE mobile application, BACnet MSTP protocol for building automation systems, Modbus RTU RS-485 port, and SAGE module connectivity supporting Modbus TCP, BACnet TCP/IP, BACnet MSTP, and LonWorks protocols. Thermal disinfection capability ranges from 158°F to 185°F with completion within 100 minutes and cool-down within 30 hours. The SAGE subscription provides real-time monitoring, recording, and documentation for Armstrong Hot Water Systems. The worksheet certifies that these characteristics are essential to Government requirements and will not restrict acquisition to a single manufacturer.
