Water Temperature Control—Groups of Fixtures—Thermostatic

Rada 320

Rada Thermostatic Mixing Valve of “sealed for life” disposable cartridge construction. Compact design and top and/or bottom blended water outlet make Rada 320 ideal for recessed enclosure, plumbing chase and utility/mechanical room installation.

Complete operating mechanism of valve is enclosed in a durable polymer cartridge for ease of field maintenance. Powerful internal mechanism and non metallic wetted parts resist mineral deposition.

Capable of close temperature control at diverse flow rates between 1 gpm (3.8 lpm) 24 gpm (91 lpm). Able to blend 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 320D

A derivative assembly of the standard Rada Thermostatic Mixing Valve of “sealed for life” disposable cartridge construction. Compact design and top and/or bottom blended water outlet make Rada 320 ideal for recessed enclosure, plumbing chase and utility/mechanical room installation.

• Adjustable single temperature lockout
• Thermal shutdown mode upon inlet supply failure

Rada 320-FMC

Rada Thermostatic Mixing Valve for remote/secure cabinet mount “dead leg” group fixture control. Rada 320 is ideal for this application due to its low service, single “sealed for life” disposable cartridge construction, low inlet to outlet temperature differential requirement and low flow single fixture control capability.

Rada 320-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 320-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 320-FMC can be specified/ordered with the following piping configurations under the following model numbers:

Top inlets/bottom outlet 320-FMC-TB
Bottom inlets/bottom outlet 320-FMC-BB
Bottom inlets/top outlet 320-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 320-SMC.
