Product Features
AT series pneumatic actuators incorporate the latest technology with full conformance to ISO5211, DIN3337, VDINDE-3854, and NAMUR specifications. The extruded high-intensity aluminum body features a honed internal surface with hard anode oxygenation for durability and low friction.
Key advantages include compact construction, external stroke adjustment (±5°), and options for double acting or spring return (normally-open/normally-close) configurations. The pre-compressed load spring ensures safe mounting, while die-cast aluminum pistons and end caps provide strength with light weight.
