Worcester Controls 1039SNR3 Pneumatic Actuator

The Worcester Controls 1039SNR3 Pneumatic Actuator (Series 39) provides 90-degree quarter-turn valve automation with pneumatic spring-return actuation and a rack-and-pinion mechanism. Designed for industrial process automation, it commonly drives ball valves, butterfly valves, and dampers in chemical processing, water treatment, steam systems, and manufacturing lines. Key specifications include a maximum operating pressure of 120 PSI, torque output of 170 in-lbs, and an air supply range of 40–120 PSI, with ISO valve mounting configuration and stainless steel guide rods plus a corrosion-resistant housing. It supports about 5 million cycles before overhaul and operates from -40°F to 180°F, using clean compressed air or non-corrosive gas for pneumatic on/off control.
