Introduction
Scope of the Manual
This manual describes and provides instructions and
parts list for Type 1098-EGR or Type 1098H-EGR
regulator complete with a standard P590 Series
fi lter and either a 6350 Series regulator, a 61 Series
pilot, or a Type Y600AM pilot. The Type 1806 relief
Types 1098-EGR and 1098H-EGR

valve is also covered when a 61 Series pilot is used.
Instructions and parts lists for monitoring pilots and
other equipment used with this regulator are found in
separate manuals.
Description
Types 1098-EGR and 1098H-EGR regulators provide
economical and accurate pressure control in a
wide variety of applications: natural gas distribution
systems; fuel gas supply to industrial boilers, furnaces,
ovens, and mixers; and large commercial/industrial
establishments such as shopping centers and schools.
They are also used in plant air service and in liquid
service where a slow stroking time (approximately
30 to 90 seconds) is desired on both opening and
closing the main valve.

Page 2: Specifications
The Specifications section lists pressure limitations and other specifications for various Types 1098-EGR and 1098H-EGR constructions. Specifications for a given regulator as it originally comes from the factory are stamped on nameplates located on both the actuator and main valve body, while the pilot control spring range is displayed on the pilot spring case, and the pilot restriction code is stamped on the pilot body (S = standard gain, L = low gain, and H = high gain). - Page 3 Types 1098-EGR and 1098H-EGR Table 2.
