Design and Construction Overview

Design:
The POWER TECHNOLOGY (PT) pneumatic rack and pinion actuator by AIR TORQUE is designed for reliability and high performance. It features a wide product range for cost-effective sizing, patented innovations, and compliance with global specifications. Advanced protective surface treatments are used to prevent wear and corrosion.

Construction:
The actuator includes an extruded aluminum body with corrosion protection, a dual piston rack and pinion design for compactness and high-cycle life, and reversible rotation. It has independent travel stop adjustments for precise valve alignment, a patented anti-blowout drive shaft, and a multifunctional position indicator. The design allows for field conversion between double acting and spring return models. High-quality bearings and seals provide a wide operating temperature range, and stainless steel fasteners ensure corrosion resistance. The actuator conforms to ISO 5211, DIN 3337, and VDI/VDE 3845 specifications.

Range of Options and Accessories:
Options include six types of corrosion protection, stainless steel drive shafts, and extreme temperature applications. Accessories available are solenoid valves, switch boxes, proximity switches, gear boxes, and positioners.

Metric Torque Ratings:
Detailed torque ratings for various actuator models and spring sets under different supply pressures are provided, showcasing the actuator's performance capabilities.

Technical Notes:
Actuator moving times are specified under controlled test conditions, with variations expected in field applications.
