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 Sin-
gle Acting/Spring Return or Double Acting/Direct Acting
actuators. Double Acting/Direct Acting actuators use the
5/2 configuration (Fig. 1-2) and requires no adapter kit. Sin-
gle Acting/Spring Return actuators use the 3/2 configuration
(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 sep-
arately). This kit includes an airflow plate, O-ring seal and
longer screws.
Installation
Valves are designed to be operated within the technical charac-
teristics specified on the nameplate. Bray reserves the right to
change or modify product design without prior notice.
These valves are designed to operate with filtered 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 qualified personnel only.
Before mounting the solenoid spool valve assembly on the
actuator it must be configured 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 figures 1 and 2.
For 3/2 Single Acting/Spring Return 3-Way: the 4-way to
3-way conversion kit (flow 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 figures 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”
configuration. In this configuration no adapter kit is required.
Pneumatic Connections
Connect supply pipes in accordance with the markings on
the nameplate
5/2 Double Acting/Spring Return configuration:
Supply pressure to Port 1 (¼”NPT). Exhaust both Ports 3
and 5 (1/4”NPT).
3/2 Single Acting/Spring Return configuration: 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 filter 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.

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