APPLCIATION
Powers #11 Water Mix Regulators are typically used for automatic
control of domestic or process water tempering. The self-actuated
regulator can easily be installed in any convenient location. Among
its applications are: two-temperature hot water systems, jacket
water cooling of engines or compressors, and many other industri-
al processes. Below are two typical applications.
The three-way regulator can also be used for bypass control, in lieu
of a diverting valve, but it must be piped as a mixing valve, with two
inlets and one outlet.
WARNING:
In domestic water system, a safety shutdown
device should be installed in conjunction with a #11
regulator. Failure of the #11 thermal system will
result in a constant rise in temperature (or constant
high temperature ) of the fluid which you are trying
to control.
