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
⁄
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 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
2
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.
