The Contractor shall label all new valves using valve tags using the same convention that the Project currently uses, see below:

Valve Number System:

a. Valve Designation Every "Control Valve" will have a three-symbol designation.

( a ) ( b ) ( c ) Example: S- SA- 1

First Symbol ( a ) LOCATION. Indicates the general location of the valve on the Project. "S" indicates the service bay.

Second Symbol ( b ) SYSTEM. Identifies the system which the valve controls. "SA" is service air.

Third Symbol ( c ) NUMBER. Is the individual number of the valve in a given system. "1" identifies a particular service air valve in the Service Bay, generally the first valve in the system.

b. Location Symbol ( a ):

S Service Bay A Assembly Bay (Erection Bay) 1 Main Unit Bay No. 1 2 Main Unit Bay No. 2 3 Main Unit Bay No. 3 FP1 Fish Pump Bay No. 1 OS Oregon Shore WS Washington Shore NL Navlock SP Spillway (including Center and North Non-overflow Dams) FF Fish Facility

c. System Symbol ( b ):

GO Governor Oil LO Lubricating Oil HO Hydraulic Oil TO Transformer Oil TBO Thrust Bearing Oil TBW Thrust Bearing Cooling Water KL Kidney Loop Oil OP Oil Purifier DO Disposal Oil (Dirty Oil) SA Service Air GA Governor Air BA Brake Air CW Generator Cooling Water TW Transformer Cooling Water XW Compressor Cooling Water GW Turbine Gland Water PW Potable Water (Domestic Water) RW Miscellaneous Raw Water FW Fire Protection Water CO CO2 Fire Protection UD Unwatering Drainage SD Sanitary Drainage BD Building Drainage GN Governor Nitrogen Closure System TN Transformer Nitrogen

d. Number Symbol ( c ):

Gives the number of a valve in it's system. Generally, the first valve in each system will be number 1, and valves following should generally be numbered consecutively. The same number is used for valves having an identical function, but in a different location:

for example, 11-CW-2 and 12-CW-2. Also, if identical function valves are in the same general location, the valve number may carry letter suffixes such as 2A and 2B, etc.

Valves are generally numbered consecutively from downstream to upstream and shore to center non-overflow dam section.

The transition from one piping system to another or one unit to another may typically be designated by indicating both systems or unit locations, i.e. A-PW/XW-72 or 1/2-GO-7.

e. Use on Schematic Drawings: Where a valve designation is typical for more than one generating unit, the location symbol is left blank meaning the designation is applicable to any generating unit by inserting the unit number. ( -SA-1)

f. "Control Valve" Designation: Any valve which can be manually operated to control the system fluid during normal operations of the plant.

g. Application: The valve numbering system is applicable to all control valves in all project piping systems.
