Applications
■
Powers #11 Regulators are used to automatically control the
temperature of a fl uid. The self-actuated regulator can easily be
installed in any convenient location. Among its applications are:
hot water and steam systems, fuel oil heaters, heat exchangers,
air drying rooms, and many industrial processes. Below are two
typical applications.
#11 CD valves are well suited to heating applications where
the steam inlet pressure is under 50 psig and good shutoff is
required.
