IA250D F05+F0714 Pneumatic Actuator

IA250D F05+F0714 Pneumatic Actuator is suitable for rotary valves with a double-piston rack and pinion structure, providing stable output torque (0-8000 N.m). The cylinder body is made of aluminum alloy or stainless steel. The bottom shaft mounting hole of the pneumatic actuator complies with the ISO5211 standard, while the air source port, top of the output shaft, and mounting holes at the top adhere to the NAMUR standard. The same specifications are available in double-acting and single-acting (spring return) versions, with rotation direction selectable as clockwise or counterclockwise according to valve requirements. Electromagnetic valves, positioners, limit switches, and manual operation devices can be installed based on user needs.

IA250D F05+F0714 Pneumatic Actuator features a high-quality extruded aluminum alloy cylinder body with precision-machined internal bore and external surfaces treated with hard anodizing (or anodizing + Teflon coating under special conditions), ensuring extended service life and a low friction coefficient. The integrated design allows all double-acting and single-acting actuator models to share the same cylinder body and end caps, facilitating easy conversion between action modes by adding or removing springs. The modular pre-loaded safety spring set enables convenient and safe installation or adjustment of the number of springs, both during assembly and on-site. Two separate adjustment screws on the external side provide exceptional convenience for actuators already mounted on valves, allowing adjustment of the valve open and closed positions. For full-stroke adjustment, longer adjustment screws are additionally provided on both end caps. The multi-functional position indicator offers on-site visual indication, complies with VDI/VDE3845 and NAMUR standard slots, and supports the installation and output of all accessories such as limit switch boxes, electro-pneumatic positioners, and position sensors (e.g., Pepperl+Fuchs, Turck). The air source interface conforms to NAMUR standards, allowing direct installation of NAMUR standard solenoid valves. Composite bushings on the back of the rack, piston guide rings, and output shaft bearings prevent metal-to-metal friction, enhance lubrication, and ensure low friction and long service life. All fasteners are made of stainless steel for long-term corrosion resistance. Connection parts comply with the latest ISO5211 and DIN3337 (F03-F25) standards, ensuring interchangeability and universality in product installation.
