Flowserve 20F39SN6 R7 Pneumatic Actuator Valve Assembly

The Flowserve 20F39SN R7 Pneumatic Actuator Valve Assembly pairs a rugged F39 Series twin-piston, spring-return rack-and-pinion actuator with a 1-1/2 inch stainless steel ball valve for reliable, quarter-turn valve automation. It operates from 40 to 120 PSI (maximum 120 PSI) with an output torque of 272 in-lbs at 60 PSI, and supports a 500 PSI CWP rating and temperatures up to 400°F, making it suitable for demanding process environments. Constructed with an F316L stainless steel valve body and 316L trim, TFE seats, a corrosion-resistant coated aluminum actuator housing, and stainless steel hardware, it features ISO 5211 and NAMUR mounting compatibility for easy integration and retrofit. Common applications include water and wastewater treatment, chemical processing, steam systems, compressed air lines, and general industrial automation where dependable pneumatically actuated flow isolation is required.
