Stronach ™ Pneumatic Actuators

Heavy Duty Carbon Steel Pneumatic Actuators

Heavy Duty Carbon Steel Pneumatic Actuators are available as heavy-duty double acting (DA) carbon steel pneumatic actuators and heavy duty spring return (SR) pneumatic actuators. Supply media for both of these actuators are filtered compressed air, inert gases and technical gas.

Both the DA and SR heavy-duty carbon steel pneumatic actuators are ATEX and SIL 3 certified. This means that installation in potential explosive environments is allowed and customers are guaranteed the highest levels of functional safety. For the DA version, torque is directly proportional to the actuator’s air supply pressure, while for the SR the return torque is spring dependent only.

These pneumatic actuators work on the Scotch yoke system with rolling friction, which means it converts linear motion to a rotary system with no gears, which reduces friction between piston and shaft, reducing wear on the parts. Friction between these parts is reduced even more through the energised and self-lubricated strips used.

  • Standard temp range -20 to 80° C / high temp range -20 to 150° C
  • Air supply pressure from 3 bar up to 8.5 bar
  • 90° rotation angle with -5° – 95° stroke adjustment
  • Bronze bushes reduce wear
  • Actuator can be powered with gases

Stronach™ Linear actuator

Features:

  • Decades of Reliable Service
  • High Thrust Capabilities
  • Long Stroke Lengths
  • Compact and Lightweight
  • Simple Maintenance

The Stronach ™ spring cylinder linear actuator is a powerful, high-performance pneumatic actuator that provides positive throttling or on-off operation for automatic control valves. Most cylinder sizes are designed for supply pressures up to 150 psi (10.3 Bar). Using a spring to provide failsafe operation, this actuator is completely field reversible for air-to-open or air-to-close operation without additional parts. The positioner supplies air to both sides of the piston, providing stiff, precise movement and high-frequency response.
