Goldfields Pipeline-Limitorque

By 1895 it was clear that the problem of supplying water to the growing population on the goldfields required a radical solution. It took the brilliant mind of Engineer-in-Chief, Charles Yelverton O’Connor, to come up with the solution; however, his proposal was met with disdain from many.

AVFI Plug Valve-Limitorque QX Actuator

Another completed package with Diana Grande giving it her seal of approval. The plug valve was free-issued by AVFI, mounting, set up, calibration and protective coatings were all completed in house making it a simple process of bolting into the pipework and connecting the power once at site.

Limitorque – The Worlds First Actuator.

In the 1920’s an inventor named Payne Dean was issued a patent for a machine which had the unique ability to sense and subsequently limit output force in a precisely controlled manner, he coined the acronym “Limitorque” which aptly described the ability of the device to “limit the torque” Below is a drawing of that first actuator, model D100, it became the foundation product with principals that are instilled in modern day actuators today, these principals have also been adopted by the majority of other actuator manufacturers, testament to the Limitorque original design.
