Main Features
- Dual piston rack and pinion design for compact construction,symmetric mounting positon,high-cycle life and fast opeation,reverse rotaton can be accomplished in the field by simply inverting the pistons.
- Multiple bearings and guides on racks and pistons,low friction,high cycle life and prevent shaft blowout.
- Modular preloaded spring cartridge design.with coated spring for simply versatile range,greater safely and corroson resistance, longer cycle life.
- Fully machined teech on piston and pinion for accurate low backlash rack and pinion engagement,maximum efficiency.
- Stainless steel fasteners for long term corrosion resistance.
- Fullconformance to the latest specification;ISO5211.DIN3337 and Namur or product interchange ability and easy mounting of solenoids, limit switches and other accesories.
Product Application
AT series Pneumatic Actuator is made of dual pistons driven by racks and pinions. There are two models. One is Dual Acting model, and the other is Spring Return model, which can suit various flammable, corrosive, dusty, strong magnetic field, radiation, vibration corrosive environment indoor or outdoor.
