 ¢ Extruded aluminum ASTM6005 body with bath internal and external corrosion protection having honed cylinder surface for longer life and low coefficient of friction.
 ¢ Dual piston rack and pinion design for compact construction, symmetric mounting position, high-cycle fife and fast operation, reverse rotation 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 coatedspring for simple versatile range, greater safely and corrosion resistance, longer cycle life.
 ¢ Fully machined teeth on piston and pinion for accurate low backlash rack and pinion   engagement, maximum efficlency. Stalnless steel fasteners for long term corroslon resistance
 ¢ Full conformance to the latest specifications: IS05211,DIN 3337 and Namur or product inter changeahility and easy mounting of solenoids, limit switches and other aocessodes.
