NOTES:
1. This reference table lists valves that are acceptable because of
capacity and piping connection type. Actual valve selection for spe-
cific mode (N.O. or N.C.) and capacity rating (C V ) to meet jobsite
conditions must be made by field personnel.
2. Valve size ( 1 ⁄ -, 5 ⁄ -, and 7 ⁄ -in. OD) designates the matching tub-
2 8 8
ing size.
Use price page package 18-2 or 18-4 for selecting
OD valves. Use price page package 18-3 or 18-5 for
valves.
3. The 1 ⁄ -in. and 5 ⁄ -in. OD valves are used primarily on 42C (ceiling)
2 8
and 42V (vertical) room fan coil units. The
recommended for use on 42D (ducted) units.
4. Flare connections are 45° SAE flare with body threaded for stand-
ard flare nuts.

5. The C V capacity rating is the gpm flow through a valve at 1.0 psi
pressure drop.
EXAMPLE: A 2.5 C V valve has a flow of 2.5 gpm at 1.0 psi pres-
sure drop.
As flow changes, pressure drop can be determined by the
formula:
Actual gpm
P =
C V
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-

fied will permit removal of the entire pneumatic valve for field 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 final acceptance.
8. Consult factory on all applications involving valves with thermo-
static actuators or built in pneumatic thermostats.
