Worcester Controls 1039NR6 Pneumatic Actuator

The Worcester Controls 1039NR6 is a Series 39 double-acting pneumatic rotary actuator designed for quarter-turn valve automation in industrial process control. This rack-and-pinion pneumatic actuator operates at 40–120 PSI and delivers a 90-degree rotation for precise valve positioning, with a torque output up to 62,835 in-lbs across the Series 39 platform. It features ISO 5211 and NAMUR mounting compatibility, a 1/8 inch NPT air port, and a corrosion-resistant Coro-lube coated aluminum housing with a polished stainless steel guide rod and stainless fasteners for durability in demanding environments. Built for reliability, the unit supports approximately 5 million cycles before overhaul and operates across −40°F to 180°F. Commonly used with ball valves, butterfly valves, and dampers in chemical processing facilities, water and wastewater treatment plants, steam systems, compressed air applications, food processing equipment, and general manufacturing automation where dependable pneumatic valve actuation is required. Typical applications include valve automation, retrofit projects, and replacement maintenance, offering adjustable limit stops and modular accessory mounting to tailor the actuator for specific installations.
