1.1 Purpose
This manual provides a guideline for Valve Operating System (VOS) engineering on selection
of the Filter Regulators.
1.2 Filter Regulators (FR) or Air Preparation Units
Filter Regulators (FR) or Air Preparation units are essential for installation/control systems,
therefore the correct functionality is very important.
It is observed that the size and the installation of valves, fittings and others in a
control systems are carefully engineered, but the Filter Regulators (FR) seldom
get the same importance even though this element is equally necessary for a good
functionality and service life duration of the installed Valve Operating System (VOS),
including the actuator.
