Series F39 Pneumatic Actuator - WCENIM2036-00 05/15
3.6.6 Determine position indication. Buttons on position indi-
cator are set up to show valve closed on in-line mounting,
i.e., pistons together on actuator. If different indication is
required:
• Check which visual indication is required.
• Check that indicator, when located on actuator shaft,
will show correct indication.
• To change indication, on size 10 to 20 push out
(remove) red and white buttons and reassemble in
opposite positions. For sizes 25 and above remove the
complete indicator and orientate to the correct position.
• Locate indicator on actuator shaft flats. Press firmly
until location nibs snap into recess on actuator shaft.
4 AIR SUPPLY AND ELECTRICAL
INSTALLATION
4.1 Air Supply:
The Series F39 Actuator is factory lubricated. For optimum
operation, the use of filtered and lubricated air is recom-
mended.
4.2 Air Supply Pressure:
Standard double-acting actuators require 40–120 psig
supply air. Spring-return actuators require 80–120 psig
supply air. Spring-return actuators can also be set up
to operate on supply air pressures ranging from 40–80
psig by using fewer springs. See “Rebuilding Instruc-
tions”, Spring-Return Actuator, paragraph 1 on page 13
for proper number and location of springs for reduced
supply air pressures.
WARNING: Air pressure greater than 120 psi must not be
applied.
4.3 Air Supply Connections:
4.3.1 No Integral Solenoid:
Double-Acting (N Models) – Connect air supply lines to
both NPT (
1 /
8
” on size 05, ¼” on sizes 10–50) ports.
Spring-Return (SN Models) – Connect air supply line to
the outboard NPT (
1 /
8
” on size 05, ¼” on sizes 10–50)
port.
For sizes 10–50, the ports are on the solenoid end cap.
The solenoid end cap is the one on the right end of the
actuator when looking at the nameplate. For 05 size only,
the ports are on the solenoid block interface plate on back
of actuator when looking at the nameplate. For size 05
spring-return it is on the back and near center of actuator.
4.3.2 With Integral Solenoid:
Connect air supply line to the NPT ( 1 /
8
” on four-way
double-acting blocks, ½” on threeway spring-return
blocks) port on the solenoid block.
4.4 Recommended Tubing Sizes:
In order to provide sufficient flow of supply air to the
Series F39 actuator, the following tubing sizes are recom-
mended:
Actuator Size
Runs Up To
4 Ft. Long
Runs Over
4 Ft. Long
05, 10, 15, 20, 25 1 /
8
¼
30, 33, 35, 40, 42, 45 ¼ 3 /
8
50 ¼ ½
5. Air Consumption
The following chart shows the amount of pressurized (80
psig) air consumed per stroke in cubic feet. To determine
the total amount of air consumed per complete cycle
for double-acting actuators, simply add the volumes for
both the opening and closing strokes together; for spring
return units, the total volume of air consumed is the
volume shown for the opening stroke.
