INTRODUCTION

The REGAL 3 is a direct-operated, spring set point pressure regulator,
used for supplying industries and commercial businesses.
As an option, it can be equipped with a slam shut type VSX2 or OS2
which permits the gas flow to be cut off rapidly and totally in the case of
under or over outlet regulator pressure.
As a standard feature for outlet pressure settings inferior or equal to
180 mbar, a relief valve is provided.
On request, this relief valve may be disconnected and replaced by a
dampener.
Upon request, for pressures 180 mbar <Pa <= 1100 mbar, the REGAL 3
can be equipped with a relief valve.
This relief valve can be factory adjusted.
