AXEL LARSSON执行器AL77系列介绍
AL77是一种用于90°阀门操作的气动执行器。AL77可作为双作用(DA)或单作用(SR)。AL77设计了一个内部杠杆（Scotch Yoke原理），在操作开始和结束时提供更高的扭矩。
AL 77 is a pneumatic actuator for 90° operation of valves. AL 77 is available as double acting (DA) or single acting (SR). AL 77 is designed with an internal lever (the Scotch Yoke principle) which gives a higher torque at the start and end of the operation.
