Series 2800 Precision Globe Control Valves are available with a
variety of actuators and accessories. These actuators and accessories
have separate instructions. For complete control valve installation,
operation, and maintenance instructions see also the instructions
for the actuator and accessories in use.
VALVE IDENTIFICATION
To use these instructions it is necessary to identify the configuration
of the valve. Factory assembled control valves have a nameplate
mounted on the actuator. The valve’s part number (P/N) is present
on the plate. The part number represents the configuration of the
control valve. To identify the valve’s type, size, actuator, accessories,
and other characteristics decode the part number using configura-
tion table. If the information is incomplete, incorrect, or not pres-
ent contact the factory with the valve serial number listed on the
plate. (See Information Present on Control Valves section for location
of part number, serial number, and other important information on
valve.)
