意大利AIRTORQUE AT401UDA气动执行器顶部安装孔尺寸符合NAMUR标准；气源接口尺寸符合NAMUR标准；底部安装孔尺寸符合ISO5211、DIN3337标准,方便安装电磁阀限位开关等附件。
意大利AIRTORQUE AT系列气动执行器分为单作用和双作用两种类型;执行开关动作都通过气源来驱动执行,叫做双作用;只有开或者关是气源驱动，相反的动作则由弹簧复位，叫做单作用。重量轻、体积小、输出力矩大，广泛应用于石油、化工、冶金、制药、电力等行业中的生产过程中。
意大利AIRTORQUE AT401UDA气动执行器是以压缩空气为动力,通过活塞齿条的直线运动带动输出轴的齿轮传动，以转角行程输出的气动执行器。有双作用及单作用型，广泛适用于球阀、蝶阀、旋塞阀等角行程阀门的开关和调节，也可适用于其他回转场合，是实现工业管道自动化控制的理想装置。
意大利AIRTORQUE AT401UDA气动执行器广泛适用于天然气、油品、化工、冶金、造纸、电力、矿业、印染、生物制药、日用化工，食品材料，水处理及空气处理等行业的流体自动控制或调节控制，与自动化仪表配套使用。
The top mounting hole size of Italian AIRTORQUE AT401UDA pneumatic actuator meets NAMUR standard; The size of air supply interface shall conform to NAMUR standard; The size of the bottom mounting hole shall comply with ISO5211 and DIN3337 standards, so as to facilitate the installation of solenoid valve limit switch and other accessories.
Italian AIRTORQUE AT series pneumatic actuators are divided into two types: single acting and double acting; The actuating switch action is driven by the air source, which is called double action; only opening or closing is driven by air source, and the opposite action is reset by spring, which is called single action. Light in weight, small in volume and large in output torque, it is widely used in the production process of petroleum, chemical, metallurgy, pharmacy, electric power and other industries.
Italian AIRTORQUE AT401UDA pneumatic actuator is a pneumatic actuator driven by compressed air, which drives the gear transmission of the output shaft through the linear movement of the piston and rack, and outputs in angular travel. It has double action and single action types, and is widely applicable to the opening and closing and adjustment of ball valves, butterfly valves, plug valves and other angular travel valves, as well as other rotary occasions. It is an ideal device for automatic control of industrial pipelines.
Italian AIRTORQUE AT401UDA pneumatic actuator is widely used for automatic control or regulation of fluid in natural gas, oil products, chemical industry, metallurgy, papermaking, power, mining, printing and dyeing, biopharmaceutical, daily chemical industry, food materials, water treatment and air treatment industries, and is used together with automatic instruments.
