Oldest operating Moog servo valve
29 April 2016
The Industrial Group of Moog has declared Doug Bitner, manager for the University of Saskatchewan’s College of Engineering Fluid Power Lab, the winner of its contest to find the oldest operating Moog servo valve after he sent in a video showing lab equipment running with a Moog 21 Series servo valve manufactured in 1963.
According to Bitner, the University of Saskatchewan is noteworthy for having one of the few undergraduate fluid power labs in North America. The winning servo valve is part of a single closed-loop test system Bitner’s students and instructors use for aerospace and industrial experiments.
“We’ve done endurance testing in the lab on agricultural equipment frames, up to 1 million cycles for high pressure and the Moog valve still exhibits good characteristics," said Bitner.
