Moog 62-229

The Moog 62-229 is a precision servo valve manufactured by Moog. This electrohydraulic servo valve is engineered for high-accuracy motion control in demanding industrial and aerospace hydraulic systems.

Overview

The Moog 62-229 servo valve converts low-power electrical command signals into precisely controlled hydraulic flow, enabling accurate position, velocity, and force control of hydraulic actuators. Moog servo valves are recognised worldwide as the industry benchmark for electrohydraulic control performance, with decades of proven reliability in the most demanding applications.

This valve features Moog's proprietary torque motor and nozzle-flapper pilot stage design, providing exceptional dynamic response with low threshold and minimal hysteresis. The precision-lapped main spool ensures consistent flow gain characteristics and tight null specifications, critical for high-performance closed-loop servo systems.

The 62-229 is designed for installation on standard hydraulic manifolds and is compatible with a wide range of Moog and third-party servo amplifiers and motion controllers. The valve is rated for continuous industrial duty with proven reliability in high-cycle, high-pressure applications.
