Thermostatic
Model 320
Thermostatic Mixing Valve of "sealed for life" disposable
cartridge construction. Compact design with top and/or bottom
blended water outlet makes the Model 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) and 24 gpm (91 lpm). Able to blend
within 5°F (2°C) of either inlet supply due to "low seepage"
across internal proportioning mechanism.
