Double Action Actuators DA Pneumatic Rotary Actuator for Valve on off Valve Rotary Actuators for Ball Butterfly Valve Features for new type rack and pinion pneumatic actuator 1. rack and pinion design 2. Integral design, double-acting and single-acting(spring return) options available. 3. The extruded high-quality aluminium alloy cylinder body, has long service life and low friction coefficient by hard anodic oxidation treatment. 4. Multi-functional position indicator, field visual indication, in line with VID/VIE3845, NAMUR standard slot, can install and output all accessories, such as limit switch box, electrical positioner, position sensor. 5. The air source interface meets the NRMAR standard, and NUMAR standard solenoid valve can be installed directly. 6. Composite material bearings reduce metal friction and increase lubrication, prolong service life. 7. All fasteners are stainless steel with long-term corrosion resistance. 8. The connection conforms to ISO5211, and DIN3337 (F03-F25) makes the production and installation interchangeable and universal. Design & Construction Of AT Series Double Acting Pneumatic Actuator The extruding high-intensity aluminum body possesses a honed internal surface coated with hone anode oxygenation for long life, low coefficient of friction and swift performance. Excellent, compact and modernized construction along with multi-specifications make the selection both economic and beneficial. All acting surfaces adopt high-quality bearings, resulting in low friction, high cycle life, and no noise. The two independent external travel stop adjustment bolts can easily and precisely adjust ±5°at both open and close directions
