Rada 320
Rada Thermostatic Mixing Valve of "sealed for life" disposable
cartridge construction. Compact design with top and/or bottom
blended water outlet makes 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.

event of individual thermostat failure
