NOTES:

1. This reference table lists valves that are acceptable because of capacity and piping connection type. Actual valve selection for spe-

ci®c mode (N.O. or N.C.) and capacity rating (C ) to meet jobsite

V

conditions must be made by ®eld personnel.

2.Valve size (1¤2-, 5¤8-, and 7¤8-in. OD) designates the matching tub- ing size.

Use price page package 18-2 or 18-4 for selecting 1¤2-in. or 5¤8-in. OD valves. Use price page package 18-3 or 18-5 for 7¤8-in. OD valves.

3.The 1¤2-in. and 5¤8-in. OD valves are used primarily on 42C (ceiling) and 42V (vertical) room fan coil units. The 7¤8-in. OD valves are recommended for use on 42D (ducted) units.

4.Flare connections are 45° SAE ¯are with body threaded for stand- ard ¯are nuts.

5.The CV capacity rating is the gpm ¯ow through a valve at 1.0 psi pressure drop.

EXAMPLE: A 2.5 CV valve has a ¯ow of 2.5 gpm at 1.0 psi pres- sure drop.

As ¯ow changes, pressure drop can be determined by the formula:

Actual gpm 2

P =

CV

6.Restrictions imposed by limited piping enclosures often require that the valve manufacturer's recommendation for obstruction free serv- ice clearances be waived. Service/isolation valves normally speci- ®ed will permit removal of the entire pneumatic valve for ®eld serv- ice if necessary.

7.Certain combinations of piping accessories and control valves have proven unacceptable in the past, therefore the factory must re- serve the right of review for ®nal acceptance.

8.Consult factory on all applications involving valves with thermo- static actuators or built in pneumatic thermostats.
