Puretorq

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, significantly lower cost and lower maintenance cost compared to our competitor's actuator.

Puretorq's life cycle has been tested to millions of cycles in Double Acting, Fail-Safe and Spring Return versions, lasting longer than the coventional 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".
