SERIES 62 Solenoid Pilot Valve
Operation & Maintenance Manual
Manual Number OM-62-001 • Date: March 24, 2014 8:28 AM • Page 1 of 2
Description
The Bray Series 62 solenoid pilot spool valves have an aluminum
body and mounting interface pattern conforming to NAMUR.
The Bray Series 62 is IP65, NEMA 4, 4x.
The Bray Series 62 solenoid can be used either with Single Acting/Spring Return or Double Acting/Direct Acting
actuators. Double Acting/Direct Acting actuators use the
5/2 conguration (Fig. 1-2) and requires no adapter kit. Single Acting/Spring Return actuators use the 3/2 conguration
(Fig. 3-4) and require the use of a conversion kit to convert
4-Way to 3 -Way, part number 62-1250-22500-536 (sold separately). This kit includes an airow plate, O-ring seal and
longer screws.
Installation
Valves are designed to be operated within the technical charac-
teristics specied on the nameplate. Bray reserves the right to
change or modify product design without prior notice.
These valves are designed to operate with ltered air or inert
gas (e.g. Nitrogen). Do not exceed the maximum allowable
pressure of 130 psi (9 bar), and minimum operating pressure of
22 psi (1.5 bar). Operating ambient temperature range is a +5°F to
+140° F (-15° C to +60° C). Installation and maintenance of the
solenoid valve must be carried out by qualied personnel only.
Before mounting the solenoid spool valve assembly on the
actuator it must be congured for the required function.
For 5/2 Double Acting/Direct Acting 4-Way: no con-
version kit is required. The solenoid spool valve assembly
mounts directly to the actuator with 2 each (#10-32 -1 1/8” or
m5 x 0.8, 28mm depending on actuator drilling) screws and
O-rings as shown in gures 1 and 2.
For 3/2 Single Acting/Spring Return 3-Way: the 4-way to
3-way conversion kit (ow plate, O-ring and 2 each (#10-32
-1 3/8” or m5 x 0.8, 28mm depending on actuator drilling)
longer screws, part # 62-1250-22500-536 (sold separately)
may be used. Install the conversion kit as shown between the
solenoid pilot valve and actuator as shown in gures 1 and 2.
It however is not uncommon to use a 4-way solenoid to op-
erate a Single Acting actuator, in a “spring to close air assist”
conguration. In this conguration no adapter kit is required.
Pneumatic Connections
Connect supply pipes in accordance with the markings on
the nameplate
5/2 Double Acting/Spring Return conguration:
Supply pressure to Port 1 (¼”NPT). Exhaust both Ports 3
and 5 (1/4”NPT).
3/2 Single Acting/Spring Return conguration: Supply
pressure to Port 1 (¼”NPT), Exhaust to Port 3 (¼” NPT).
It is recommended to protect Port 5 (when not used) with a
vented pipe plug or screen, do not plug completely.
Manual override
The solenoid is equipped with a Manual Override:
To engage Override; depress the red manual override button and
rotate 90° clockwise, the override will lock in place, causing the
spool valve to activate. The button can also be pressed to activate
the spool momentarily. (Please refer to Figs 1, 2, and 3 on page 2
for the location of the manual override button).
To disengage Override; rotate the red manual override button
counterclockwise 90°, the manual override button will pop out
and the spool will deactivate and be returned to the normal posi-
tion. (Please refer to Figs 1, 2, and 3 on page 2 for the location of
the manual override button).
In order to prevent injury or damage and to ensure correct
remote operation of the pilot solenoid valve, the Manual
Override must be returned to the disengaged position by
rotating it 90° counterclockwise, to normal (disengaged)
before returning to remote operation of the pilot solenoid.
General Recommendations concerning pneumatic
connections: connect pipes with the required functions in
accordance with this documentation and port markings on the
valve. Make sure no foreign matter enters the system. Use of a
coalescing lter regulator is recommended.
Correctly support the supply piping to avoid subjecting the
solenoid spool valve assembly to mechanical stress, when
tightening, avoid using the valve as a lever. Use proper tools and
locate wrenches as close as possible to the connection point. To
avoid damage of the equipment DO NOT OVER TIGHTEN pipe
connections.
Electrical Connections
IP65/NEMA 4,4X 3 wire ying lead (2+ ground/earth)
Red power, Yellow/green: ground/earth

General recommendations for electrical connections:
electrical connections are only to be made by trained
personnel and in accordance with the applicable regulations
and standards.

Before work, switch off the electrical power supply to
de-energize all components
Depending on the voltage, electrical components must be
provided with a ground/earth connection and satisfy local
regulations and standards.
The Bray Series 62 solenoid valve is designed for continuous duty service. To avoid any possibility of damage or
injury do not touch the solenoid which can become hot
under normal operating conditions. If the solenoid valve
is easily accessible, the installer must provide protection
against accidental contact.

Maintenance.
Prior to any maintenance work or returning to operation, shut
off supply to the pilot solenoid valve, depressurize and vent
the valve in order to prevent injury or damage.
Cleaning: maintenance of the valve depends on the oper-
ating conditions. They must be cleaned at regular intervals.
During servicing, the components must be checked for excessive wear. If operation cycle is slow, ensure proper supply
pressure and that there is no unusual noise or leak detected.
Sound emission: the sound emission depends on the appli-
cation, supply medium and nature of the equipment used.
Exact determination of the sound level can only be carried
out by the user having the valve installed in their system.
Preventive maintenance: Operate the pilot solenoid
valve monthly to check function. Should any difculties or
questions arise during installation and maintenance, please
contact a Bray representative.
Troubleshooting:
Incorrect supply pressure: check the supply pressure,
Minimum air supply – 22 psi (1.5 bar)
Maximum air supply - 130 psi (9 bar)
Tools Required
Phillips (cross drive) screwdriver, to assemble and disassem-
ble solenoid coil to pilot valve
Small at blade screwdriver, to engage disengage manual red
close button.
5/32”or 4mm hex screwdriver (Allen wrench), to fasten the
solenoid pilot valve to pneumatic actuator.
