Moog contest to find oldest operating servo valve

"Moog’s servo valves have a legendary reputation for reliability, and it’s not uncommon to find our valves in service for 25 years or more in tough environments like steel production, gas turbines and industrial machinery,” said Gary Parks, group vice president and general manager – industrial services at Moog Inc.

In 1951 William C. Moog, Jr., developed the first commercially viable servo valve. Servo valves transform a digital or analog signal into a hydraulic output such as flow or pressure.

"We’re celebrating our reliability and anniversaries in Europe, while having fun by challenging people to find the oldest operational Moog servo valve,” Gary Parks.

The contest is simple and open to anyone who can find a Moog servo valve in operation on a machine. Here’s how it works:

Using a smartphone, take a photo of the valve including the serial number on the nameplate. Moog will use this information to check the date of the valve.
