Hearken Die Casting Aluminum pneumatic actuator is a 90° Double acting or Spring return rack and pinion system, which has been designed for the actuation of all type of 1/4 turn valves or 1/4 turn applications. Drive conforming to ISO5211 square and star dimensions. The actuator is suitable for mounting a full range of accessories, such as limit switches, solenoid valves, positioners and manual override gearbox. Hearken pneumatic actuators can be found in a range of applications such as petrochemical industry, food and beverage, steel production, pharmaceuticals and plastics manufacturing.

Discription
Die casting aluminum HPA body with both 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 onstruction,symmetric mounting position,high-cycle life 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 coated spring for simple versatile range,greater safety and corrosion resistance,longer cycle life. Fully machined teeth on piston and pinion for accurate low backlash rack and pinion engagement,maximum
efficiency,stainless steel fasteners for long term corrosion resistance.
