Watts 152SS SeriesPROCESS REGULATORS
Sizes 1⁄2", 3⁄4" and 1" (15, 20 and 25mm)
This design offers highly sensitive response to reduced pres-sure changes and maintains fullest possible volume withoutappreciable reduced pressure drop. They are used success-fully on applications such as oil lines, testing fixtures, auto-claves, steam tables, steam irons, single radiators, vulcaniz-ers, sterilizers, and process lines.An exclusive, feature which has been added at no extra costis a "sensitivity adjuster" which eliminates any vibrating condi-tion which may arise from critical flow requirements.
