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.
