Industrial 10-39 Double-Acting Pneumatic Actuator

The Industrial 10-39 Double-Acting Pneumatic Actuator from Worcester Controls (Flowserve) is a 90-degree rack-and-pinion, double-acting actuator designed for automated quarter-turn valve positioning in process-control systems. It combines a 1/2 BMP valve (4446PMSE R2EWP1500) with a Lenz gauge that provides integrated pressure indication, featuring a gauge range of 0–5000 PSI for direct monitoring. Operating pressure up to 120 PSI and a 1/4 inch NPT air port support reliable performance in demanding environments, with threaded industrial process connections and a 1/2 inch valve size for straightforward integration. Construction uses a corrosion-resistant coated aluminum housing with stainless steel hardware and stainless guide rods, delivering durability in harsh facilities, while direct mounting and modular accessory mounting with adjustable travel stops enable field customization. The unit’s precise actuator mechanism, a dual piston rack-and-pinion design, ensures repeatable 90-degree rotation for valve isolation and flow control in water, steam, chemical processing, and general industrial automation setups. Weighing about 7.81 lbs, it is built for approximately 5 million cycles before overhaul and operates over a temperature range of 0°F to 160°F using clean compressed air or non-corrosive gas as the operating medium. This combination of actuation, pressure indication, and rugged construction makes it suitable for process automation in chemical plants, water treatment facilities, and manufacturing environments requiring reliable pneumatically actuated valve control.
