Hydraulics Online Control Expertise: Moog electrohydraulic valves and components for industrial, mobile and aerospace hydraulic systems

Moog first ventured into manufacturing aircraft and missile components in 1951. Today, whether on land, sea, in the air or in space, their ground-breaking technologies allow machines to be controlled with astonishing precision and accuracy.

Moog was founded in the United States in the western part of New York State, but has expanded to have sales, engineering, and manufacturing facilities in twenty-six countries. The company designs and manufactures electric, electro-hydraulic and hydraulic motion, controls and systems for applications in numerous industries, including: aerospace, construction, power generation, marine, defence, motorsport and healthcare. All of these are applications where precise control of velocity, force, acceleration and fluid flow are critical.

Their ground-breaking, challenging work has been integral to several notable projects. One high profile example is enabling NASA’s Mars Rover to land safely and helping to support breakthrough advances in aerospace and development technology.

Moog offer a comprehensive range of products and technologies, which are more than capable of providing solutions to even the toughest of problems. Their product portfolio incorporates servo and proportional valves and durable, quiet and high performance radial piston pumps (RKP). Despite their existing achievements, they continue to invest in future technologies that are believed to have a great impact across many industries.
