Water Temperature Control—Recirculation Systems—Thermostatic

Rada 40R

Rada Thermostatic Mixing Valve is designed specifically to be installed as the primary control valve within a pumped recirculation system. Capable of maintaining safe, accurate water temperatures during both peak and zero-demand “idling” periods. With a Rada 40R installed as the primary temperature controller within a pumped recirculation system, there will be a zero minimum blended water flow rate/draw-off requirement. The Rada 40R features a unique integral thermostatic return limiter that maintains recirculating water temperatures within the circuit. Thermostatic return limiters eliminate the requirement for a fitted aquastat and reduce cycling wear and tear on the circulating pump.

Operational Specifications

• Dual thermostatic elements provide redundancy in the event of individual thermostat failure
• Typical system temperature control +/-5°F
• Single temperature locking feature (removable key)
