Worcester Controls 1039SN6R6 Pneumatic Actuator

The Worcester Controls 1039SN6R6 Pneumatic Actuator (Series 39) is a rack-and-pinion pneumatic rotary actuator designed for quarter-turn valve automation and precise flow control in industrial process systems. It uses a pneumatic spring-return mechanism with 90-degree rotation, operating up to 120 psi (air supply range 40–120 psi), and supports ISO 5211 and NAMUR mounting for versatile installation. Built with a corrosion-resistant coated aluminum housing, polished stainless steel guide rod, and stainless steel fasteners, it features adjustable limit stops and modular accessory mounting, rated for approximately 5 million cycles before overhaul and a temperature range of -40°F to 180°F. Commonly paired with ball valves, butterfly valves, or dampers, it serves chemical processing, water and wastewater treatment, steam systems, food processing, and other industrial automation applications requiring reliable pneumatic valve actuation.
