Moog launches contest to find oldest operating servo valve

The industrial group of Moog, a precision control component manufacturer, has launched a contest to find the oldest operating Moog servo valve.

The company will also be sponsoring monthly drawings to give people with newer valves a chance to participate.

The contest is part of a celebration of the 50th anniversary of Moog’s operations in Europe.

‘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,’ says Gary Parks, group vice president and general manager of industrial services at Moog.

In 1951 William C. Moog, Jr., developed the first commercially viable servo valve.

Servo valves transform a digital or analogue 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,’ Parks says.

The contest is simple and open to anyone who can find a Moog servo valve in operation on a machine 

To participate, using a smartphone take a photo of the valve including the serial number on the nameplate – which Moog will check the manufacturing date of the valve – and upload the photo and complete a short form at

The grand prize is an Amazon Voucher for $500, and Moog will award additional Amazon vouchers for the second prize and third prize.

Every month additional $50 Amazon Vouchers will be given to drawn participants.

The contest ends on 29 February, 2016.
