Types 63EG and 1098-63EGR
2
Specifications
Specifications for various Types 63EG and 1098-63EGR constructions are listed on Specifications section
and Tables 1 to 4. The specifications for a given construction as it originally comes from the factory are
stamped on nameplates located on the main valve body and the upper diaphragm case of the actuator for a
Type 1098-63EGR construction. The pilot control spring range appears on the pilot spring case and the pilot
restriction code is indicated by a letter stamped on the bottom of the pilot body next to the tapped side outlet: an
S for the red standard-diameter (No. 57 drill size) restriction, an L for the blue large-diameter (No. 47 drill size)
restriction for liquid service or an H for the yellow small-diameter (No. 70 drill size), high-gain restriction.
