Styling, strength, compactness, and simplicity of design have been combined to produce the Bray Series 92 direct acting and the Series 93 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 92/93 actuators are rack and pinion, opposed-piston actuators available in two versions: double acting for rotation of 90°, 135° and 180°, and spring return for 90° rotation.

The Series 92/93 actuators were designed primarily for pneumatic operation up to a maximum pressure of 140 psig (10 Bar) and for temperature ranges of -4°F to 200°F (-20°C to 93°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 92/93 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



Bray actuators comply with ISO 5211 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.
