PURETORQ Inc. specialises in the design and manufacture of high performance, lightweight composite and aluminium actuators in double acting and spring return configurations.
PURETORQ patented its vane-type, fixed seal, rotary pneumatic actuator, recognising the need for a robust and long lasting quarter-turn valve actuation.
Actuator Benefits;
Simple Design
Fewer parts than conventional Rack & Pinion or other Vane type designs improves reliability, extends product life and reduces maintenance costs.
External Single Acting Spring Return Unit – sealed, non-breathing housing protects spring in corrosive environments
Suitable for Modulating
Single moving vane is the only moving part of the actuator and is comprehensively integrated with the shaft. Zero hysteresis from the actuator to the valve stem occurs Unlike Rack & Pinion shaft, Puretorq’s shaft is constructed symmetrically allowing for better balance thereby mitigating unwanted friction and improving actuator life.
NAMUR Solenoid Valve Benefits;
- For use with compressed air (lubricated or non-lubricated), instrument air and nitrogen
- 5/2 and 3/2 function selectable via 180º rotation of single adaptor plate for use
on both single and double acting actuators - Corrosion resistant construction with standard manual override
- Direct mounting conforms to NAMUR VDI/VDE 3845 standard
- Exhaust feedback - provides spring chamber with instrument air preventing corrosion
- Unique patented Poppet valve technology provides high flow, fast response, high
temperature range and multimillion cycle life reliablity
