This design offers highly sensitive response to reduced pressure
changes and maintains fullest possible volume without appreciable
reduced pressure drop. They are used successfully on applications
such as oil lines, testing fixtures, autoclaves, steam tables, steam
irons, single radiators, vulcanizers, sterilizers, and process lines.
An exclusive, feature which has been added at no extra cost is a
“sensitivity adjuster” which eliminates any vibrating condition which
may arise from critical flow requirements.
