Simple Design

Puretorq's simple design results in far fewer parts than conventional Rack & Pinion or other Vane type designs. This results in better reliability, longer life, signiï¬�cantly lower cost and lower maintenance cost compared to our competitor’s actuator.
Puretorq Vane Type Actuator Other Vane Type Actuator Typical Rack & Pinion

Patented Fixed Tri-Seal

Puretorq's life cycle has been tested to millions of cycles in Double Acting, Fail-Safe and Spring Return versions, lasting longer than the conventional Rack & Pinion actuator. Air pressure is used to create the sealing due to the V-shape of the Tri-seal. The air pressure produces a tight seal at the contact of "seal to vane" and "seal to housing”.
