Water Temperature Control—Groups of Fixtures—Thermostatic

Rada 425

Rada 425 Thermostatic Mixing Valve for institutional group fixture water temperature control. Compact design and top and/or bottom blended water outlet make Rada 425 ideal for recessed enclosure, plumbing chase and utility/mechanical room installation.

Powerful internal mechanism and stainless steel operating mechanism resist mineral deposition.

Capable of close temperature control at diverse flow rates between 2 gpm (7.5 lpm) and 49 gpm (185 lpm). Able to blend to within 5°F (2°C) of either inlet supply due to “low seepage” across internal proportioning mechanism.

Operational Specifications

• Dual thermostatic elements provide redundancy in the event of individual thermostat failure.
• Typical outlet temperature control +/-2°F
• Adjustable maximum temperature limit stop
• Adjustable single temperature lockout
• Thermal shutdown mode upon inlet supply failure

Rada 425D

A derivative of the standard Rada 425 Thermostatic Mixing Valve for institutional group fixture control. Compact design and top and/or bottom blended water outlet make Rada 425 ideal for recessed enclosure, plumbing chase and utility/mechanical room installation.

• Typical outlet temperature control +/-2°F
• Adjustable maximum temperature limit stop
• Adjustable single temperature lockout
• Thermal shutdown mode upon inlet supply failure

Rada 425-FMC

Rada Thermostatic Mixing Valve (TMV) for remote/secure cabinet mount “dead leg” group fixture control. Rada 425 is ideal for this application due to its low service, low inlet to outlet temperature differential requirement and low flow single fixture control capability.

Rada 425-FMC is supplied as standard* fully assembled and pressure tested in an 26" x 30" x 10" stainless steel recessed cabinet with a 2" flange. Cabinet has a polished stainless steel piano-hinged door with a keyed cylinder lock.

Rada 425-FMC is supplied as standard under this model number for top inlet hot and cold water supplies and a top outlet with a left-hand hinged door as indicated in adjacent drawing.

Rada 425-FMC can be specified/ordered with the following piping configurations under the following model numbers:

Top inlets/bottom outlet 425-FMC-TB
Bottom inlets/bottom outlet 425-FMC-BB
Bottom inlets/top outlet 425-FMC-BT

* Note cabinet options under technical specifications.

NOTE: Available as above in a Surface Mounted Cabinet of the same size and specification, less recess flange, under model number 425-SMC.
