POSITIONING
This valve is designed to perform properly when mounted in any position.
However, for optimum life and performance, the solenoid should be mounted
vertical and upright so as to reduce the possibility of foreign matter accu-
mulating in the core tube area, -
MOUNTING
For mounting dimensions, refer to Figure 1.
PIPING
Connect piping according to markings on valve body. Refer to flow dia-
ams provided, Apply pipe compound sparingly to male pipe threads only;
1f applied to valve threads, it may enter the valve and cause operational dif-
ficulty. Pipe strain should be avoided by proper support and alignment of

piping, When tightening the pipe, do not use valve or solenoid as a lever,
Wrenches applied to valve body or piping are to be located as close as pos-
sible to the connection point.
To insure proper operation of the valve, the pressure and exhaust lines must
be full area without restriction, and a minimum differential pressure as
stamped on the nameplate (10 psi) must be maintained between pressure
and exhaust at the moment of changeover, Air reservoirs must have ade-
quate capacity to maintain the minimum pressure during changeover. To
check pressure during changeover, install a pressure gage in the pressure
connection as close to the valve as possible,
IMPORTANT: For the protection of the solenoid valve, install a strainer or
filter suitable for the service involved in the inlet side as close to the valve
as possible. Periodic cleaning is required depending on service conditions.
See Bulletins 8600, 8601 and 8602 for strainers.
FLOW CONTROLS (Speed or Metering Devices}
Flow control valves (speed or metering devices) may be added to allow full
unrestricted flow in one direction and control flow in the opposite direc-
tion, These flow control valves must be located in Cylinders ““A’" and for
“B* piping between the solenoid valve and the cylinders. IMPORTANT: Do
not install flow control speed and/ox metering devices or any type of restric-
tive device in either the Pressure “‘P* (inlet) connection or in the Exhaust
“HA” or “EB” (outlet) connections of the valve, Restricting these lines or
outlets may cause valve malfunction,

WIRING |
Wiring must comply with Local and National Electrical Codes, For valves
equipped with an Explosion-Proof/Watertight Solenoid Enclosure, the
electrical fittings must be approved for use in the approved hazardous
locations. Housings for all solenoids are provided with accommodations or
connections for 1/2 inch conduit, To facilitate wiring, the solenoid enclosure
may be rotated 360°. The general purpose solenoid enclosure may be ro-
tated by loosening the pipe adapter ox removing the retaining cap or clip.
CAUTION: When metal retaining clip disengages, it will spring upward.
Rotate solenoid enclosure to desired position. Tighten pipe adapter to a
maximum torque of 90 inch-pounds [10,2 newton meters) or replace re-
taining cap or clip, To rotate the Explosion-Proof/Watertight Solenoid En-
closure, loosen cover, Rotate the solenoid enclosure to desired position and
tighten cover, Torque cover to 135 + 10 inch-pounds [15,3 + 1,1 newton
- Meters].
NOTE: Alternating Current (A-C) and Direct Current (D-C) solenoids are
built differently, To convert from one to the other, it is necessary to
change the coll and core spring,
- SOLENOID TEMPERATURE
Standard catalog valves are supplied with coils designed for continuous
duty service. When the solenoid is energized for a long period, the solenoid
enclosure becomes hot and can be touched with the hand only for an in-
stant, This is a safe operating temperature. Any excessive heating will be
indicated by the smoke and odor of burning coil insulation.
MAINTENANCE
WARNING: Turn off electrical power supply and depressurize valve before
making repairs. It is not necessary to remove the valve from the pipe line
for repairs. However, piping or tubing must be removed from Pressure **P”
connection and Exhaust “EB? connection on air and liquid constructions.
CLEANING
A periodic cleaning of all solenoid valves is desirable. The time between
cleanings will vary depending on medium and service conditions. In general,
if the voltage to the coil is correct, sluggish valve operation, excessive noise
or leakage will indicate that cleaning is required, Clean valve strainer or
filter when cleaning solenoid valve,
PREVENTIVE MAINTENANCE
1. Keep the medium flowing through the valve as free from dirt and for-
eign material as possible,
2. While in service, operate the valve at least once a month to insure
roper opening and closing. , e
3. Periodic inspection (depending on medium and service conditions) of
internal valve parts for damage or excessive wear is recommended.
Thoroughly clean all parts. Replace any parts that are worn or damaged.

IMPROPER OPERATION
1. Faulty Control Circuit; Check the electrical system by energizing the
solenoid, A metallic click signifies the solenoid is operating. Absence
of the click indicates loss of power supply, Check for loose or blown-
out fuses, open-circuited or grounded coil, broken lead wires or splice
connections. 0
Bumed-Out Coil: Check for open-circuited coil. Replace coil if neces-
least 85% of nameplate rating.
Incorrect Pressure: Check valve pressure. Pressure to valve must be
within range specified on nameplate.
5. Excessive Leakage: Disassemble valve and clean all parts, Replace worn
or damaged parts with a complete Spare Parts Kit for best results.
COIL REPLACEMENT
Tum off electrical power supply and disconnect coil lead wires, Determine
solenoid construction, General Purpose or Explosion-Proof/Watertight.
Proceed in the following manner:
General Purpose {Refer to Figures 2 and 3.)
Disconnect tubing connection at top of solenoid enclosure, Unscrew
pipe adapter and remove spring washer. For air only construction, re-
move retaining cap or clip. CAUTION: When metal retaining clip dis-
engages, it will spring upward. ‚ ‚ |
2, Slip nameplate, cover, spring washer, insulating washer, coil and in-
sulating washer off the solenoid base sub-assembly. Insulating washers
(2) are omitted when a molded coil is used, ‚
3. Reassemble in reverse order of disassembly paying careful attention to
exploded views provided for identification and placement of parts.
4. Maximum torque for the pipe adapter is 90 inch-pounds [10,2 newton
meters]. ;
CAUTION: Solenoid must be fully reassembled as the housing and internal
parts are part of and complete the magnetic circuit. Place an insulating
washer at each end of coil, if required,
Explosion-Proof/Watertight {Refer to Figure 1.)
1. Disconnect tubing connection at top of solenoid enclosure and un-
screw pipe adapter,
2, Unscrew cover with nameplate and retaining ring attached. Two
wrenching flats are provided on the housing to hold it securely in
place while the housing cover is being removed or replaced.

meters]. Maximum torque for pipe adapter is 90 inch-pounds [10,2
newton meters].
CAUTION: Solenoid must be fully reassembled as the housing and internal
parts are part of and complete the magnetic circuit, Place an insulating
washer at each end of coil, if required.
NOTE: Installation and maintenance of explosion-proof equipment re-
quires more than ordinary care to insure safe performance. All finished sur-
faces of the solenoid are constructed to provide a flameproof seal. Be sure
that the surfaces are wiped clean before replacing, If watertight, as well as
explosion-proof is a requirement, grease the joints including the under side
of the solenoid base sub-assembly flange and intemal threads of the housing
cover with DOW CORNING(® 111 compound ox an equivalent high grade
silicone grease.
