INSTALLATION
Check the product label for correct catalog number and voltage.
POSITIONING/MOUNTING
The solenoid 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 accumulating in the core tube
area.
IMPORTANT: For the protection of the solenoid valve, install a strainer or filter
suitable for the service involved on the inlet side of the valve as close to the valve as
possible.
WIRING
Wiring must comply with local codes and the National Electrical Code. To facilitate
wiring, the solenoid may be rotated 360°.
1. The open-frame solenoid is provided with DIN terminals to accommodate the
plug connector kit.
2. Remove center screw from plug connector. Remove the screw from the terminal
block and using a small screwdriver, pry the terminal block from the connector
cover.
3. Use #12-18 AWG stranded copper wire rated at 90°C or greater for connections.
Strip the wire leads back approximately 1/4˝ for installation in socket terminals. The
use of wire-end sleeves is also recommended for these socket terminals. Maximum
length or wire-end sleeves to be approximately 1/4˝. Thinning of the ends of the
lead wires is not recommended.
4. Thread wire through gland nut, gland gasket, washer and connector cover. NOTE:
Connector cover may be rotated in 90° increments for alternate positioning of cable
entry.
5. Check DIN connector terminal block for electrical markings. Then make electrical
connection to terminal block according to markings on it. Snap terminal block into
connector cover and install the terminal block and center screw.
6. Install the plug connector on the solenoid.
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 should not be touched.
CLEANING
A periodic cleaning of all solenoid valves is desirable. The time between cleaning 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 cleaning
is required. Clean valve strainer or filter when cleaning the solenoid valve.
PREVENTIVE MAINTENANCE
1. Keep the medium flowing through the valve as free from dirt and foreign material
as possible.
2. While in service, operate the valve at least once a month to insure proper opening
and closing.
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 fuses, open-circuit or grounded coil,
broken lead wires or spliced connections.
2. Burned-Out Coil: Check for open-circuit coil. Replace coil if necessary.
3. Voltage: Check voltage across the coil leads. Voltage must be at least 85% of
stated rating.
SOLENOID REPLACEMENT
1. Disconnect the conduit, coil leads, and grounding wire.
2. Remove the center screw from the DIN plug connector. Disconnect the DIN plug
connector from the adapter. Remove the locknut, DIN terminal adapter, and gasket
from the solenoid.
3. Remove the coil from the plunger tube assembly.
4. Reassemble reversing the previous steps.
MAINTENANCE/REPAIR
Upon final installation of the Series SSV, no routine maintenance is required. The
Series SSV is not field serviceable and should be returned if repair is needed. Field
repair should not be attempted and may void warranty.
WARRANTY/RETURN
Refer to “Terms and Conditions of Sales” in our catalog and on our website. Contact
customer service to receive a Return Goods Authorization number before shipping the
product back for repair. Be sure to include a brief description of the problem plus any
additional application notes.
Turn off electrical power supply and depressurize valve before
making repairs. It is not necessary to remove the valve from the
pipelines for repairs.
