Worcester Controls 2539R Double Acting Pneumatic Actuator

The Worcester Controls / Flowserve 2539R Double Acting Pneumatic Rotary Actuator (Series 39) provides 90-degree rack-and-pinion actuation for precise quarter-turn valve automation in industrial process systems. This double-acting pneumatic actuator uses clean compressed air or non-corrosive gas for on/off valve control and rapid cycling across chemical processing, water treatment, steam systems, and manufacturing lines. Key specifications include a 40–120 PSI operating pressure range (maximum 120 PSI), an anodized aluminum housing with stainless steel guide rods and fasteners, ISO 5211 and NAMUR mounting, adjustable travel stops, and modular accessory mounting, with a cycle life of approximately 5,000,000 cycles and a temperature range from -40°F to 180°F. Designed for compatibility with ball valves, butterfly valves, and dampers, it supports automated valve positioning and process flow isolation in industrial process automation, retrofit, and replacement maintenance applications.
