Worcester Controls 25E39SXXD24D Pneumatic Actuator Assembly

The Worcester Controls 25E39SXXD24D Pneumatic Actuator Assembly is a rugged rack-and-pinion valve actuator with an integrated LK39S XXD 24D limit switch package, delivering precise 90-degree quarter-turn valve control for industrial process automation. Operating from 40–120 PSI (maximum 120 PSI), it provides pneumatic on/off actuation with electrical feedback to deliver reliable position indication in chemical processing, water treatment, steam systems, and manufacturing lines. Built with a corrosion-resistant anodized aluminum housing, stainless steel guide rods and fasteners, it supports ISO 5211 and NAMUR mounting, and features adjustable travel stops plus modular accessory mounting for versatile valve integration. The dual-piston mechanism drives the 90-degree rotation, the limit switch assembly is configured for 24V operation, and the unit withstands -40°F to 180°F in standard configuration with an approximate 5 million cycles before overhaul. Compatible with ball valves, butterfly valves, and dampers, it supports remote monitoring and accurate process flow isolation across industrial applications requiring dependable valve automation and electrical position indication.
