Oldest operating Moog servo valve

29 April 2016

The Industrial Group of Moog 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.

Moog launched the contest last September as part of a celebration of the 50th anniversary of the company’s operations in Europe. 

The winning servo valve is part of a single closed-loop test system students and instructors use for aerospace and industrial experiments: Bitner says: “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.”

In second place was Walter Andreas from IABG, an analysis and testing company, with a 22 Series Moog valve manufactured in 1966 running on a test application in Germany. Third place is shared by John Shannon of TATA Steel’s CPP Trostre Works in the UK and Tom Gecse of US Steel in Canada.
