Introduction
Scope of the Manual
This manual provides instructions for installation,
startup, adjustment and maintenance for Type 114PL
Pressure Reducing System. For pilots maintenance,

Manual D103711X012.
Product Description
Type 114PL
Type 114PL high-pressure reducing and low-flow
system is a battery of three Type BSL85 pilots (see
Instruction Manual, D103711X012) where two of them
are pneumatically loaded and the third one is spring-
loaded. It is designed for high-pressure reduction with
low-flow conditions.
Type RPE (Electric Heater)
Type RPE can be used together with the Type 114PL.
Type RPE is used for reheating gas supplying
pressure reducing regulator pilots. Type RPE avoids
the inconveniences caused by freezing which
occur during large pressure drops. (See Instruction
Manual, D103694X012).
