Product Description XM Series Double-Action Pneumatic Actuator Product DescriptionWorking Principle The XM Series double-action pneumatic actuator operates through bidirectional air supply to drive rotational motion. Compressed air enters through port A to push the dual pistons to move axially, converting linear displacement into rotational motion of the output shaft via precision rack-and-pinion meshing, enabling clockwise rotation (valve opening). When air is supplied through port B, the pistons reverse direction, driving the output shaft to rotate counterclockwise (valve closing). In case of air supply failure, the actuator maintains its current position, ensuring system stability during transient interruptions.Structural Features Modular Design: The cylinder block and end caps of double-action models share dimensional compatibility with spring-return variants, allowing on-site conversion by adding/removing springs. This modularity reduces spare part inventory and enhances field adaptability.Standardized Interfaces: Compliant with ISO 5211 (mounting flange), DIN 3337 (drive shaft), and VDI/VDE 3845 (NAMUR top interface), ensuring seamless integration with solenoid valves, positioners, and limit switches. The standardized design guarantees interchangeability across global industrial systems.Premium Materials & Finishing:Cylinder: Extruded aluminum alloy (6061-T6) with hard anodized coating (≥50μm thickness) for superior corrosion resistance (salt spray test ≥500 hours).Inner Cylinder Surface: Precision honed to Ra 0.8μm, minimizing friction and extending service life.Output Shaft: Nickel-plated alloy steel (42CrMo) with integral forging, achieving tensile strength ≥900MPa for high torque resistance.Fasteners: 316 stainless steel to prevent galvanic corrosion in humid environments.Performance Parameters Torque Output: Ranging from 5 Nm to 12,992 Nm (at 6 bar supply pressure), covering actuation requirements for 2" to 48" valves.Operating Pressure: 2.5-8 bar (maximum 10 bar for short-term peak loads), with linear torque output proportional to supply pressure.Temperature Rating:Standard version: -20°C to +80°C (NBR seals)Low-temperature version: -40°C to +80°C (silicone rubber seals)High-temperature version: -15°C to +150°C (FKM seals)Stroke Adjustment: Equipped with dual external micrometric adjustment screws, enabling ±4° calibration at both end positions to ensure precise valve seating.Performance Advantages High Efficiency: Rack-and-pinion transmission efficiency ≥90%, minimizing air consumption while delivering rapid response (actuation time: 0.5-5 seconds for 90° rotation, depending on model).Durability: Designed for ≥1,000,000 cycles under rated conditions, with piston seals featuring low-friction PTFE composites to reduce wear.Environmental Protection: IP66/IP67 ingress protection rating (per IEC 60529), with static seals utilizing O-rings and dynamic seals U-cup structures to prevent air leakage (leakage rate ≤0.5 Nm3/h at 6 bar).Application Fields Ideal for automated control of 90° rotary valves (ball valves, butterfly valves, plug valves) in industries such as petrochemicals, water treatment, food & beverage, and power generation. Particularly suitable for scenarios requiring frequent actuation and precise position retention, such as process pipeline regulation and batch production systems.
