Designing features

ASTM316L,316,304,stainless steel pneumatic actuator with electro-polish finish offer excellent resistance to most corrosive chemicals as well as industrial atmospheres.
Dual piston rack and pinion design for compact construction, 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 safely and corrosion resistance, longer cycle life.
Fully machined teeth on piston and pinion for accurate low backlash rack and pinion engagement, maximum efficiency.
The two independent external travel stop adjustment bolts can adjust ±5°at both open and close directions easily and precisely.
Stainless steel fasteners for long term corrosion resistance.
Full conformance to the latest specifications:ISO5211,DIN3337 and Namur or product interchangeability and easy mounting of solenoids, limit switches and other accessories.
