Introduction
Scope of Manual
This instruction manual includes installation, maintenance and parts information for NPS 2 through 4 CCV-N fuel gas
control valves. These valves are used in gas turbines which meter the fuel gas to the combustion chamber of the
turbine and provide linear flow with the ability to choke very quickly at a low pressure drop. Refer to separate manuals
for instructions covering the actuator and accessories.
Do not install, operate, or maintain CCV-N valves without being fully trained and qualified in valve, actuator,
and accessory installation, operation, and maintenance.
To avoid personal injury or property damage, it is
important to carefully read, understand, and follow all the contents of this manual, including all safety
cautions and warnings.
If you have any questions about these instructions, contact your Emerson sales office before
proceeding.
