Worcester Controls 2539R-39 Pneumatic Actuator

The Worcester Controls 2539R-39 Pneumatic Actuator is a rugged rack-and-pinion actuator designed for 90-degree quarter-turn valve automation in industrial process systems. Part number 2539R, Series 39, uses a dual-piston rack-and-pinion design for reliable valve actuation and operates at 40–120 psi (maximum 120 psi) with a 90-degree rotation. It features a corrosion-resistant anodized aluminum housing, stainless steel guide rods and fasteners, ISO 5211 and NAMUR mounting compatibility, and adjustable travel stops, with pneumatic on/off control and a cycle life of about 5 million cycles. Designed for industrial process automation, it is compatible with ball valves, butterfly valves, and dampers and supports operating temperatures from -40°F to 180°F, using clean compressed air or non-corrosive gas as the operating medium. Common applications include chemical processing facilities, water treatment, steam systems, food processing equipment, and industrial manufacturing lines, where dependable valve positioning and process flow control are essential.
