Worcester Controls 2039NR6 Pneumatic Actuator

The Worcester Controls 2039NR6 Pneumatic Actuator is a rugged, Series 39 double-acting rack-and-pinion rotary actuator engineered for 90-degree quarter-turn valve automation in industrial process systems. It operates at 40–120 PSI (maximum 120 PSI) and delivers 935 in-lbs of torque for reliable valve positioning. Built for ISO 5211 and NAMUR mounting, it uses a corrosion-resistant coated aluminum housing with stainless steel guide rods and fasteners, and features adjustable limit stops and modular accessory mounting for flexible installations. This actuator provides a 90-degree rotation and supports approximately 5 million cycles before overhaul, with a -40°F to 180°F operating temperature range in standard configuration. It is compatible with ball valves, butterfly valves, and dampers, and is designed for clean compressed air or non-corrosive gas control via pneumatic on/off operation in industrial process automation systems. Commonly used in chemical processing plants, water and wastewater treatment, steam systems, and food processing equipment, it serves valve automation, retrofit, and replacement maintenance needs across industrial manufacturing lines. Common replacements include Flowserve Worcester F39 Pneumatic Actuator, Bray double acting pneumatic actuator, and Asco rack and pinion pneumatic actuator.
