I. General
WARNING
Failure to install and operate the Series 05 Gear
Operator as defined in this manual can cause
severe damage to equipment.
A. The Bray Series 05 Declutchable Manual
Override Gear Operator is typically mounted
between a valve and a Bray Series 92 Pneumatic
Direct Acting Actuator or Series 93 Pneumatic
Spring Return Actuator. It is used to permit
manual operation of the valve in case of a loss of
operating air pressure. Special caution is required
when using the Series 05 with a Series 93 spring-
return actuator. Refer to Section III, Paragraph B
of these instructions.
B. If you are ordering an S05 Gear Operator to place
in an existing assembly, confirm that sufficient
space is available in the pipeway as the override
gear adds considerable height to the valve and
actuator assembly.
Refer to www.braycontrols.com for Series 05
general dimensions.
CAUTION
C. Disconnect the air supply to the S92/93
actuator when operating the S05 gear operator.
Conversely, when the S92/93 actuator is being
operated, disengage the S05. Failure to do
so will prevent the assembly from operating
properly and may damage some equipment.
D. The clutch lever is attached to an eccentrically-
bored bearing which houses the input shaft. The
rotation of the clutch handle is restricted to 180°.
E. When the handle is at the far left position, the
gear is disengaged allowing powered operation
of the valve. Turning the handle 180° clockwise
engages the worm on the input shaft with the drive
sleeve segment gear allowing manual operation
of the valve.
F. Series 05 gear operators are internally lubricated
at the factory for the life of the product and
are sealed from the environment. No routine
maintenance is required except an occasional
check to assure that external corrosion or damage
does not prevent operation of the unit.
