The Industrial Group of Moog has launched a contest to find the oldest operating Moog servo valve and will sponsor monthly drawings to give people with newer valves a chance to participate. This contest is part of a celebration of the 50th anniversary of Moog’s operations in Europe.

“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 including steel production, gas turbines and industrial machinery,” says Gary Parks, group vice president and general manager – industrial services at Moog Inc. “We’re celebrating our reliability and anniversaries in Europe while having fun by challenging people to find the oldest operational Moog servo valve.”

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.

The contest is 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.

  • Upload the photo and complete a short form at

The grand prize is an Amazon Voucher for US$500; Moog will award additional Amazon vouchers for the second prize and third prize. Even if a contestant’s valve is not the oldest operational valve or if they have multiple valves they can still qualify to win five US$50 Amazon Vouchers that Moog will draw each month.
