| PNEUMATIC
Styling, strength, compactness
and simplicity of design have
been combined to produce the
best rotary actuator on the
market today. Bray pneumatic
actuators are rack and pinion,
opposed-piston actuators available
in two versions : double acting
and spring return. They have
a maximum pressure rating of
140 psi (10 Bar) and a temperature
range of - 13oF (-25oC) to -200oF
(95oC). Offered for the first
time to the industry are the
unique actual are the unique
actual piston guides and rings
which have a very low coefficient
of friction and absorb the side
thrusts of the piston. Other
features include internal porting
which reduces the cost of easily
damaged external tubing position
indicator and travel stop adjustments.
Our patented spring return unit
is designed with the housing
length the same size as our
double acting unit, and the
spring cartridges are inherently
safe. The standard spring cartridge
system is available for 40,
60, 80 and 100 psi services
(3,4,5,6 and 7 Bar).
ELECTRIC ACTUATORS
Bray electric actuators are
powered by a rugged high-torque,
integral, singla phase, reversible
motor. All models feature a
disengagecable manual override.
Included are two SPDT switches,
shaft position indicator, motor
overload protector and Available
in NEMA 4 OR NEMA 7 housings.
Output torque from 275 to 48,000
Ib-ins.
WORM
GEAR
For manual override of pneumatic
actuators. During pnuematic
operation of the valve, the
worm of the gear unit is disengaged.
Should the valve require opening
or closing in the event of power
loss, manual rotation of the
declutch lever will provide
a camming action and engage
th worm to the sehmented worm
the worm to the segmented worm
gear. Reverse rotation of the
lever will allow for disengagement
of the unit. Excellent for safe
handling of spring return actuators.
Available for 2” - 48”
(50mm-1200mm) valves.
