INTRODUCTION

Scope of Manual
This manual provides installation, startup, maintenance, trouble-
shooting and spare parts for the pilot series PS/79 and PS/80.
Product Description
Designed for pressure regulators control, the following types
are available:
•
PS/79 - single diaphragm pilot for pilot controlled gas
pressure regulator (active or wide-open monitor)
• - single diaphragm pilot for setting of first
PSO/79
pressure reducing step of pilot controlled gas pressure
regulator (working monitor)
•
REO/79 - single diaphragm pilot for setting of downstream
pressure reducing step of pilot controlled gas pressure
regulator (working monitor)
In case of failures, these pilots with single diaphragm will
cause a fail open reaction of the regulator.
•
PS/80 - double diaphragm pilot for pilot controlled gas
pressure regulator (active or wide-open monitor)
• - double diaphragm pilot for setting of first
PSO/80
pressure reducing step of pilot controlled gas pressure
regulator (working monitor)
•
REO/80 - double diaphragm pilot for setting of
downstream pressure reducing step of pilot controlled gas
pressure regulator (working monitor)
PS/79 and PS/80
Figure 1. Type PS/79 and PS/80 Pilots
In case of failures, these pilots with double diaphragms will
cause a fail close reaction of the regulator.
RE/79 and RE/80 versions are in accordance with specific
requirements of Italian market applications.
Tightness cover version available on request (e.g. PS/79-D
and PS/80-D).
The full range of PS pilots can be installed in the following
pressure regulators:
