Rada 32E
Rada 32E is a Thermostatic Mixing Valve of "sealed for life" disposable cartridge construction.
For Emergency Drench Showers - The Rada 32E will pass a specified minimum of 76
litres per minute (l/min) and will flow a minimum of 38 l/min from direct cold water supply in
hot failure mode at 2.7 bar (40 psi) maintained equal inlet supply pressure.
For Emergency Eye Wash Stations - For single or multiple fixture installation, the Rada 32E
will control accurately at flow rates from 76 to 8 l/min.
In flow applications between 76 and 38 l/min, the Rada 32E will pass approximately 50% of
original flow setting in hot failure mode.
In flow applications between 38 and 19 l/min, the Rada 32E will pass approximately 80% of
original flow setting in hot failure mode.
In flow applications below 19 l/min, the Rada 32E will pass approximately 95% of original
flow setting in hot failure mode.
Operational Specifications
1. Site Adjustable—Mechanical maximum-temperature limit stop and single-temperature
locking features as a function of the temperature control handle design.
2. Thermal shutdown feature is designed to protect user from unsafe water temperatures
or hot water/chemical reaction should cold supply be interrupted during use.
3. Unique constant cold water flow design ensures that in the event of a hot supply failure
the Rada 32E will allow cold water to flow to fixture.
4. Unique constant cold water flow feature allows the inlet hot water supply to be set within
a prescribed range, thus limiting the potential outlet temperature to a safe maximum in
the event of misadjustment, unauthorized tampering or thermostat failure. This feature
presumes that the correct initial commissioning was performed and that the cold water
supply has not been interrupted.
