Well Head Valve Manufacturer,
Well Head Valve Stockist
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, single
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.
