The Flowserve Worcester Controls 2039SN-R6 Pneumatic Actuator with the 2WK7066TTC R0 Ball Valve (MK510 11) is a rack-and-pinion, pneumatic spring-return actuator assembly designed for automated 90-degree quarter-turn valve actuation in industrial process control systems. It operates at 40–120 PSI (maximum 120 PSI) and delivers 335 in-lbs of output torque at 80 PSI, enabling precise valve positioning for flow isolation and process control. The valve is a WK70 series 1-1/2 inch stainless steel ball valve with an F316L body and trim, TFE seat, a CWP rating of 500 PSI, and a maximum temperature of 400°F. Mounting is ISO and NAMUR compatible, and it is compatible with water, steam, compressed air, oil, and various chemicals. Common applications include chemical processing, water treatment, steam systems, and general industrial process automation, where valve automation, retrofit, and replacement maintenance are required.
