Servicing Valve Body
Refer to figures to aid with disassembly and reassembly. Servicing
a 3-Position valve is very similar to servicing a 2-Position valve.
1. Using a clean, lint free cloth, clean the valve unit prior to servicing.
2. Using a 4 mm hex wrench for socket head, back out the three captive
mounting screws (21) until the valve unit can be removed from
the base.
!
CAUTION: Do not remove the valve body from the sandwich
block. Doing so could risk possible seal contamination. There
are no parts between the valve body and sandwich block that
require servicing.
3. On solenoid valves, loosen the two captive mounting screws (11) and
then remove the solenoid coil (9) and sandwich adapter (13) as a unit
from the operator adapter (15).
4. To remove the operator adapter from the valve body, remove its two
mounting screws (14). You will now be able to service the piston’s
seal, as well as the gasket which is located between the operator
adapter and the valve body.
5. On air operated and return operators of single solenoid valves, loosen
the two screws (23) until their end cap(s) can be removed from the
valve body (22).
6. Gently press on either end of the spool assembly until it slides out of
its bore, taking care not to scratch bore. Using a clean, lint free cloth,
clean the body bore and all sealing surfaces for gaskets prior to their
installation. Inspect bore for nicks, scratches, or surface imperfections.
If present, reduced service life is probable and future replacement
should be planned.

WARNING
To avoid unpredictable system behavior that can cause personal injury
and property damage:
•
Disconnect electrical supply (when necessary) before installation,
servicing, or conversion.
•
Disconnect air supply and depressurize all air lines connected to
this product before installation, servicing, or conversion.
•
Operate within the manufacturer’s specified pressure, temperature,
and other conditions listed in these instructions.
•
Medium must be moisture-free if ambient temperature is below
freezing.
•
Service according to procedures listed in these instructions.
•
Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understand how
pneumatic products are to be applied.
•
After installation, servicing, or conversion, air and electrical supplies
(when necessary) should be connected and the product tested for
proper function and leakage. If audible leakage is present, or the
product does not operate properly, do not put into use.
•
Warnings and specifications on the product should not be covered
by paint, etc. If masking is not possible, contact your local
representative for replacement labels.

NOTE: Solenoid operated valves, when specified with external pilot, may
have operating pressures down to vacuum in the main valve.
External pilot pressure and air pilot signals must be greater than
or equal to that in the main valve, but not outside the ratings
above.
Ambient Temperature Range:
-15°C to 49°C (5°F to 120°F)
Voltage Range:
Rated V10%, -15%
!
CAUTION: An interruption of 10 milliseconds or greater to the
power supplied to the solenoid of a solenoid operated valve
may cause the valve to shift. Provision must be made to prevent
power interruption of this duration to avoid unintended,
potentially hazardous, consequences.
Wiring Instructions
1. Follow all requirements for local and national electrical codes.
2. Remove end cover from base by backing off the two captive screws.
Reassemble cover to base by tightening screws from 0.8 to 1.0 N•m
(7 to 9 in-lbs).
