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.

AT series Pneumatic Actuators are suitable for various environments including flammable, corrosive, dusty, strong magnetic field, radiation, and vibration conditions. Ideal for industrial automation in:

• Electric power plants
• Petrochemical facilities
• Metallurgy operations
• Oil and gas processing
• Water treatment and drainage systems
• Chemical processing plants
• Mining operations
• Food and pharmaceutical production
