Output Torques to *4,**0 in-lb (4,**6 Nm)
Styling, strength, compactness, and simplicity of design
have been combined to produce the Bray
Series *2 direct acting and the Series
*3 spring return pneumatic actuators.
Engineering excellence and precision manufacturing has
produced a modular product line with reduced overall size
requirements and economic savings. In addition all Bray
accessories are fully modular and directly mount to the
actuator providing flexibility and efficiency at reduced
cost.
Bray Series *2/*3 actuators are rack and pinion,
opposed-piston actuators available in two versions: double
acting for rotation of *0°, **5° and **0°, and spring return
for *0° rotation.
The Series *2/*3 actuators were designed primarily for
pneumatic operation up to a maximum pressure of **0 psig (*0
Bar) and for temperature ranges of *4°F to **0°F (**0°C to
*3°C). For
higher and lower temperature applications, consult
factory.
All double acting and spring return units are suitable for
both on/off and throttling applications. Actuators which can
be actuated with other media such as hydraulic oil or water
are also available as an option.
The Series *2/*3 is completely enclosed and self contained.
The many features minimize maintenance and provide safe,
simple disassembly and assembly.
- Two independently adjustable travel stop screws and a cam on the output shaft to permit precise bidirectional adjustment of movement in both the open and closed positions for quarter turn valves (*5° to *5° limit adjustment)
- Integral porting
- Standard units have anodized aluminum bodies with polyester coated end caps
- Special coatings and materials available for corrosive environments
- NAMUR accessory compatible
Direct Mounting
Bray actuators comply with ISO ***1 dimensions and mount directly to Bray valves without using external linkages. Field installation is simple, misalignment is minimized and contamination buildup between valve and actuator is reduced.
