introduction
Scope of the Manual
This manual provides instructions for installation,
adjustment, maintenance, and parts ordering
information for the FL Series regulators sold in
North America.
Description
The FL Series regulators are accurate pilot-operated,
pressure-balanced, soft-seated regulators designed
for high-pressure transmission/city gate, large
capacity distribution systems, and power plant feeds.
The FL Series provides smooth, quiet operation, tight
shutoff, and long life. The regulator utilizes a main
E0820
valve actuator, a Type PRX/120 pressure reducing
pilot, and a Type SA/2 pilot supply pressure regulator.
The Type PRX/120 pilot uses inlet pressure reduced
by a Type SA/2 supply pressure regulator, as loading
pressure to operate the main valve actuator. The
outlet pressure is sensed through a control line on
the main valve actuator and also on the Type PRX
pilot diaphragm.
Specifications
The Specifications section gives some general
specifications for the FL Series regulators. The
nameplates give detailed information for a particular
regulator as it comes from the factory.
