Bray Series 92/93

Bray Series 92/93 Pneumatic Actuator


The 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 Bray 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. The Bray Series 92/93 is completely enclosed and self contained.
