Description
The Bray Commercial 92-1280-11300-532 is a double-acting pneumatic actuator intended to regulate air flow in HVAC systems. This may operate a variety of HVAC devices, including dampers, valves, and louvers, by using compressed air to extend and retract a piston rod in both directions. The piston rod of the actuator extends when compressed air is introduced to one of its ports, pushing or tugging on the attached machinery. The piston rod retracts as the airflow direction is changed, giving the operator fine control over where the equipment is positioned. For HVAC systems, this double-acting mechanism has various advantages. Double-acting actuators offer more flexibility and control than single-acting actuators, which only use springs to move in one direction.
