Digital Recirculation Valve, Brain, DRV80R

DRV80R is a fully digital recirculation valve (DRV) for "point of source" or mechanical room based installation. DRV80 is designed specifically to be the primary water temperature controller in a continuously pumped recirculating hot water system.

Operational Specifications

The enhanced accuracy possible with DRV80 digital technology, combined with its data input/output communication capability equals:

Accurate control of blended water drawn from the system at a point of use typically within +/-2°F at draw off points a minimum of 5m downstream of mixing valve during consistent system demand periods
Operational water pressure of 10 -150 psig
Minimum valve inlet to outlet temperature requirement (system recirculation temperature loss) of 2°F
Automatic shutoff of hot water flow upon cold water inlet supply failure
Automatic shutoff of hot water flow in the event of a power failure
Maintain a consistent system "idling" temperature and control "temperature creep" without the use of a manual throttling device or balance valve.
System shall not require a temperature activated pump shut-off device (aquastat).
Programmable set point range of 100-160°F (37-71°C) plus full hot/full cold
Ability to thermally disinfect at recommended temperatures
Programmable 1st level hi/lo temp alarm display
Programmable temperature error level for safety shutdown
