NOTE: Indicator is set up to show pistons
together on
actuator, i.e. valve closed when
in-line mounting - See Fig. 1.
6.1 Check which visual indication is required.
6.2 Check that indicator when located on pinion
will show correct indication.
6.3 To change indication, push out red and white
buttons and reassemble in alternative posi-
tion.
6.4 Locate indicator on pinion flats. Press firmly

7 AIR SUPPLY AND INSTALLATION
7.1 Air Supply:
The Series 40R actuator is factory lubricated.
For optimum operation, the use of filtered and
lubricated air is recommended.
7.2 Air Supply Pressure:
Standard double-acting actuators require 2–8
bar supply air. Spring-return actuators require
2.5–7 bar supply air. Spring-return actuators
can also be set up to operate on supply air
pressures ranging from 2.5–5.5 bar by using
fewer springs. See “Rebuilding Instructions”,
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 the maximum
on the label must not be applied.
7.3 Air Supply Connections:
Double-Acting – Connect air supply lines to
both BSPP (
1
/
8
” on size 05/10: ¼” on sizes
15–50) ports.
Spring-Return Models – Connect air supply
line to the outboard BSPP (
1
/
8
” on size 05/10:
¼” on sizes 15–50) port.
For sizes 10–50, the ports are on the solenoid
end cap. The solenoid end cap is the one on
the left 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.
