PS and RE Series
Regulator Pilots
• High Sensitivity
• Improved Performance
• High Accuracy
Features
Introduction
The PS Series pilots are mainly used in
natural gas applications. All PS Series
pilots are supplied with a filter (5µ filtering
degree) and built-in pressure stabilizer,
with the exception of pilots types PSO/79
and PSO/80.
The PS and RE Series pilots can be
installed in the following equipment:
• FL Series
• Cronos Series
• Type 971
Available Configurations
High-Pressure Pilot Range
Type PS/79:
Single diaphragm pilot for
pressure regulator (active or wide-open
monitor)
Type PSO/79:
Single diaphragm pilot
for setting of first pressure-reducing
step (upstream) of pressure regulator
(working monitor)
Type REO/79:
Single diaphragm pilot
for setting of second pressure-reducing
step (downstream) of pressure regulator
(working monitor)
Type PS/80:
Double diaphragm pilot for
pressure regulator (active or wide-open
monitor)
Type PSO/80:
Double diaphragm pilot
for setting of first pressure-reducing
step (upstream) of pressure regulator
(working monitor)
Type REO/80:
Double diaphragm pilot
for setting of second pressure-reducing
step (downstream) of pressure regulator
(working monitor)
Low-Pressure Pilot Range
Type PS/79-1:

pressure regulator (0.5 - 3 bar)
Type PSO/79-1:
Single diaphragm pilot
for setting of first pressure-reducing
step (upstream) of pressure regulator
(working monitor) (0.01 - 0.5 bar)
Type PSO/79-2:
Single diaphragm pilot
for setting of first pressure-reducing
step (upstream) of pressure regulator
(working monitor) (0.5 - 3 bar)
Type REOPS/79-1:
Single diaphragm pilot
for setting of second pressure-reducing
step (downstream) of pressure regulator
(working monitor) (0.01 - 0.5 bar)
Type REO/79-2:
Single diaphragm pilot
for setting of second pressure-reducing
step (downstream) of pressure regulator
(working monitor) (0.5 - 3 bar)
