Single-Point and Zoned/Group Control Systems—Thermostatic

Rada^® 40

The Rada^® 40 thermostatic mixing valve is suitable for accurate water temperature control in single open-outlet or “dead leg” multiple point-of-use industrial process applications. It is also applicable for institutional group fixture or zoned temperature control when ASSE 1016-certified individual fixture controls are installed at each point of use. The valve is capable of close outlet water temperature control at flow rates between 2 and 72 gpm (7.5 and 272 lpm), and the Rada 40 may also be installed in parallel to increase outlet flow rates.

Safety, economy and comfort

• Dual thermostats for redundancy in case of individual thermostat failure
• Integral check valves prevent cross connection
• Maximum temperature locking feature with key and shutdown mode feature in the event of a cold water supply failure*
• Design and functional simplicity along with easy-access internal components reduce maintenance time
• PTFE-coated internal parts resist mineral deposits and extend service life
• Fast-acting thermostat maintains a constant outlet-water temperature by adjusting the inlet supply proportions to compensate for water temperature changes and system pressure fluctuations

*Shutdown mode is defined as a thermally driven bias toward the hot seat within the valve. This action may or may not reduce the outlet flow rate relative to the inlet supply and outlet set point temperatures. Large capacity thermostatic mixing valves [1 1/2" and 2" (40 mm and 50 mm)] cannot be guaranteed to fully shut off in the  event of a cold-water supply failure.

NOTE: The Rada 40 can also be ordered in a recessed stainless steel cabinet (40-FMC) or surface-mounted stainless steel cabinet (40-SMC).

IMPORTANT NOTE: If Rada 40 is to be used for group fixture or zoned temperature control in institutional showering, bathing or hand washing, then ASSE 1016-certified individual fixture controls must be installed at each point of use.

If the design/specification does not call for ASSE 1016-certified individual fixture fittings, then the largest group or zoned mixer suggested is Rada 425. If higher flows are required, create more groups/zones.
