diameter facing out of the bore. Move the piston sensor in the
bore and make sure the piston sensor is free to move with only
light resistance and the main valve plug and the plug spring will
push the piston sensor back up.
7. Install the retaining ring in the groove in the piston sensor
bore using internal snap ring pliers.
8 Place the range spring backup plate, the range spring, and
the spring button on the piston sensor. Lubricate the center of
the spring button and the large internal threads and chamfer of
the bonnet with Krytox.
9. Screw the bonnet onto the body and tighten it to 50 ft.lbs.
10. Lubricate and install the handwheel assembly onto the
bonnet. The handwheel assembly consists of the handwheel,
the hole plug, the adjusting screw, and the jam nut.
11. Install a filter screen in the inlet port of the body.
Prior to re-installation, the regulator should be connected to a
pressure source with a media compatible with use of the
regulator and pressurized to check for internal and external
leakage and operating characteristics.
Regulator Model Breakdown (CED Code)
Control Engineering Data is intended to provide a single source from which one can determine, in detail, the full scope of the
product line. In addition to the materials of construction, diaphragm and elastomer selection, it also provides all necessary
data regarding adjustment option and range selections. Control Engineering Data also provides a means of communicating
by way of a code number which is fully descriptive in product selection. All catalog numbers received must contain fifteen
