Bray Series 63-N4/N7 Installation & Maintenance Instructions
General Purpose/Rain Tight/Water Tight and Rain Tight/Water Tight/Explosion Proof
For S63-N4 see O&M Instructions for information
on: Operation, Positioning, Mounting, Cleaning,
Preventive Maintenance, Causes of Improper
Operation, Disassembly, and Reassembly of basic
valve.
DESCRIPTION
S63 N4/N7 Solenoid coils are thermoplastic
encapsulated pull-type for use with Bray solenoids.
These solenoids have three lead wires with one wire
for grounding and a ½ NPT male conduit connection.
S63 N4 Solenoids are designed to meet Enclosure
Type 1-General Purpose, Types 3 and 3S-Raintight,
and Types 4 and 4X-Watertight. S63 N4/N7
Solenoids meet Enclosure Types 3 and 3S-Raintight,
Types 4 and 4X-Watertight, Type 7 Explosion proof
Class I, Division 1, Groups A, B, C, & D and Type 9
- Dust - Ignition proof Class II, Division 1, Groups E,
F, & G.
STORAGE
Bray Series 63 N4/N7 are not weatherproof until
the unit is properly installed, or all conduits and
applicable port connections are sealed off and
prepared for storage. The units may be shipped with
temporary covers to prevent foreign matter from
entering through the conduit openings; however,
the user is responsible for replacing with the proper
sealing plugs to support its NEMA/IP ratings.
To prevent condensation from forming inside the unit,
maintain a near constant external temperature and
store indoors in a well ventilated, clean, dry room.
The temperature shall be between 40°F (4°C) and
85°F (29°C), with a relative humidity less than 70%.
Store units away from vibration and direct sunlight
exposure, and place units on a shelf or wooden pallet
in order to protect against dampness. Keep units
covered to protect against dust and dirt; if storing for
long term, placing the unit inside a plastic sealed bag
may be preferred.
Bray cannot accept responsibility for deterioration
caused on-site once the cover is removed or due to
improper storage.
OPERATION
When the solenoid is energized, the core assembly
is drawn into the plugnut/core tube sub-assembly.
When the solenoid is de-energized, spring force
returns the core assembly to the original position.
Enclosure Types 7 and 9 Only
!
CAUTION
To prevent re or explosion, do not install solenoid
and/or valve where ignition temperature of
hazardous atmosphere is less than 160° C. Open
circuit before disassembling.
Positioning
Solenoid may be mounted in any position.
Valve Mounting
The solenoid is assembled onto an actuator and is
rigidly supported using the actuator body mounting
provisions.
!
CAUTION
Solenoid coil wiring must be carried out by trained
personnel.
Wiring
Wiring must comply with local codes and the
National Electrical Code. The solenoid is provided
with lead wires and one grounding wire, which is
green or green with a yellow stripe. To facilitate
wiring, the solenoid may be rotated 360° in 90°
increments. To rotate solenoid, remove the four
mounting screws, reposition solenoid and replace
screws. Torque screws evenly in a crisscross manner
to 12 in-lbs [1.3 Nm].

All information herein is proprietary and condential and may not be copied or reproduced without the expressed written consent of
BRAY INTERNATIONAL, Inc. The technical data herein is for general information only. Product suitability should be based solely
upon customer’s detailed knowledge and experience with their application.
Solenoids have a ½-14 NPT male thread. For
connection to rigid metal conduit, metal type NPT
electrical ttings should be used.
!
WARNING
For the watertight and explosion proof solenoid,
electrical ttings must be approved for use in
hazardous locations.
!
CAUTION
Temperature of external casing of coil can burn
skin.
Solenoid Temperature
Standard solenoids are designed for continuous duty
service. When the solenoid is energized for a long
period, the solenoid becomes hot and can be touched
by hand only for an instant. This is a safe operating
temperature.
MAINTENANCE
!
WARNING
To prevent the possibility of personal injury
or property damage, turn off electrical power,
depressurize valve, and vent medium to a safe area
before servicing. .
Cleaning
All solenoid valves should be cleaned periodically.
The time between cleaning will vary depending on
medium and service conditions. In general, if the
voltage to the solenoid is correct, sluggish valve
operation, excessive noise, or leakage will indicate
that cleaning is required. In the extreme case, faulty
valve operation will occur and the valve may fail to
shift. Clean strainer or lter when cleaning the valve.
Preventive Maintenance
• Keep the medium owing through the solenoid
valve as free from dirt and foreign material as
possible.
• While in service, the solenoid valve should be
operated at least once a month to ensure proper
opening and closing.
• Depending on the medium and service conditions,
periodic inspection of internal valve parts for
damage or excessive wear is recommended.
Thoroughly clean all parts. Replace any worn or
damaged parts.
Causes of Improper Operation
• Faulty Control Circuit: Check the electrical
system by energizing the solenoid. A metallic
click signies that the solenoid is operating.
Absence of the click indicates loss of power
supply. Check for loose or blown fuses, open-
circuited or grounded solenoid, broken lead wires
or splice connections.
• Burned-Out Solenoid: Check for open-circuited
solenoid. Check supply voltage; it must be the
same as specied on nameplate and marked on the
solenoid. Check ambient temperature and check
that the core is not jammed. If necessary, replace
pilot valve.
• Low Voltage: Check voltage across the solenoid
leads. Voltage must be at least 85% of rated
voltage.
ORDERING INFORMATION FOR
REPLACEMENT PILOT VALVE WITH
SOLENOID:
1. Specify valve Catalog Number
2. Solenoid Catalog Number
3. Serial Number
4. Voltage
5. Frequency
