Product Overview
The OMAL DA045402S is a double-acting pneumatic actuator from OMAL’s rack-and-pinion actuator series, engineered for precise quarter-turn (90°) valve automation in industrial fluid control systems. The “DA” designation identifies a double-acting configuration, meaning compressed air is applied alternately to opposing piston chambers to drive the output shaft through both the opening and closing strokes, delivering positive torque in each direction without reliance on spring return. The model code “045” corresponds to the actuator’s torque class within the OMAL range, while “402S” denotes the specific body and interface variant. Constructed with a hard-anodized aluminum alloy body and precision-machined rack-and-pinion gearing, the DA045402S converts linear piston thrust into rotary motion with high mechanical efficiency and minimal backlash. It serves as a critical spares and accessory component for ball valves, butterfly valves, and plug valves across process, water treatment, and general industrial duty applications.
