Excelon®Plus 3/2 VALVES
Air Preparation Range
1/4”, 3/8” 82 Series
3/8”, 1/2”, 3/4” 84 Series
Installation and Maintenance Instructions
Fluid: Compressed air
Maximum supply pressure: 10 bar (145 psig)
Operating temperature*: -20 °C to +65 °C (-4 °F to +149 °F)
*Air supply must be dry enough to
avoid ice formation at temperatures
below +2 °C (+35 °F)
Typical low @ P1=6.3 bar
(90 psi) & 0.5 bar (7.25 psi)
pressure drop:
82 Series: 20.7 dm/s (44 scfm)
84 Series: 50 dm/s (106 scfm)
Typical exhaust low @ P1
= 6.3 bar (90 psi) & 0.5 bar
(7.25 psi) pressure drop:
82 Series: 22.2 dm/s (47 scfm)
84 Series: 60 dm/s (127 scfm)
Air quality: ISO 8573-1 Class 7:4 - or better
Port threads: 82 Series: 1/4”, 3/8”
84 Series: 3/8”, 1/2”, 3/4”
Exhaust port threads: 82 Series: 1/4”
84 Series: 1/2”
Thread forms: ISO G, PTF
Materials: Body: Aluminum
End Caps: Aluminum
Body Covers: ABS
Elastomers - NBR
Valve - Brass
GI-1 Always turn off and exhaust air pressure
prior to installing and servicing units.
Ensure that the air is completely exhausted
prior to beginning any actions.
GI-2 Always ensure power is removed from electrical
circuit prior to installing and servicing units.
GI-3 Electrical connections should only be made by personnel
trained and authorized to perform these operations.
GI-4 Connect piping to ports using pipe thread sealant using
pipe thread sealant on male threads only. Do not allow
sealant to enter the interior of the unit. Units should be
installed with air low in the direction of the arrow on the
body and as close as possible to the device being serviced.
GI-5 For ISO G threads do not install ittings that are longer
than 13mm for 84 Series and 10mm for 82 Series
GI-6 For Soft Start Valves install only into applications
where the downstream pressure can build up
during the initial safe pressure build up stage.
GI-7 Install exhaust silencers, with low rating greater than rated
exhaust low, into the exhaust port on the bottom of the unit.
TECHNICAL DATA
GENERAL INSTALLATION
CAUTION
Installation, commissioning, disassembling as well as repair and
maintenance must only be carried out by qualiied specialized
personnel with expertise and experience on pneumatic technology
and in case of electrical devices also electrical technology.
WARNINGS
1. These products are intended for use in industrial compressed air
systems only. Do not use these products where pressures and
temperatures can exceed those listed under Technical Data.
2. Before using these products with luids other than air, non-
industrial applications or for life-support systems, consult Norgren.

Solenoid Electrical Connection
1. Make sure the electrical voltage rating on the solenoid
matches the electrical system being connected.
See label on solenoid for voltage rating.
Solenoid Replacement
1. Turn off electrical supply and shut off air to inlet of valve.
2. Remove the electrical connector from the solenoid
3. Remove the two solenoid mounting screws (B)
4. Remove solenoid (C) and gasket (D)
5. Verify that the electrical rating on the new
solenoid matches the solenoid removed
6. Install new gasket (D) and solenoid (C), insert two screws
(B) and tighten to 4.4-6.2 in-lb. (0.5-0.7) Nm torque.
7. Attach electrical connection to solenoid and secure.
8. Restore pressure and then electrical. Test operation.
Exhaust Silencer
1. When installing the valve into an air system, installation of an
exhaust mufler (E) is recommended. The mufler needs to
low greater than the exhaust low of the valve and provide
acceptable noise reduction for the installed environment.

Warning! ISO G thread depth
Exceeding these ISO G thread depths can
result in malfunction of the unit:
Series 84: 3/8”, ½”, ¾” – max. itting insertion 13mm
Series 82: ¼”, 3/8” – max. itting insertion 10mm
1. The time required to reach full pressure is dependent
on the downstream system volume. Units shipped
from factory are set to give maximum delay.
2. To adjust delay:
a. Turn on air supply prior to applying signal to operator.
Failure to do so may cause valve to continuously exhaust.
b. Actuate the solenoid (energize the solenoid or
press and hold the solenoid override)
c. Remove environmental protection plug
(A) to access adjusting screw
d. Use a 3mm allen key to turn adjusting
screw clockwise to increase time delay and
counterclockwise to decrease time delay.
e. Reinstall environmental protection plug (A) after setting.
