Worcester Controls 2039NR3 Pneumatic Actuator

The Worcester Controls 2039NR3 Pneumatic Actuator (Series 39) is a double-acting rack-and-pinion rotary actuator designed for precise 90-degree valve positioning in automated quarter-turn valve systems. It supports valve automation and process flow control across industrial settings, including chemical processing plants, water and wastewater treatment, steam systems, compressed air lines, food processing equipment, and general manufacturing automation. This actuator is commonly used by maintenance technicians, process engineers, and system integrators for retrofit, replacement maintenance, and process upgrades that require dependable pneumatic valve actuation. Key specifications include a 40–120 PSI operating range (maximum 120 PSI), corrosion-resistant coated aluminum housing with stainless steel guide rods and fasteners, and ISO 5211 and NAMUR mounting compatibility. The unit features adjustable travel stops and modular accessory mounting for versatile installation and integration with ball valves, butterfly valves, and dampers. It delivers long-term durability with an approximate 5 million cycles before overhaul and operates across a wide temperature range from -40°F to 180°F in standard configurations. For control, it uses pneumatic on/off valve operation, making it suitable for clean compressed air or non-corrosive gas environments in industrial process automation systems.
