MOOG 209-157 Servo Valve – Overview

MOOG 209-157 is an electro-hydraulic servo valve manufactured by Moog Inc., widely used in high-precision hydraulic motion control systems. This model belongs to Moog’s mechanical-feedback servo valve family, designed for accurate control of flow, position, speed, pressure, and force in demanding industrial and aerospace applications.

Product Description

The MOOG 209-157 is a 2-stage electro-hydraulic servo valve that converts electrical input signals into precise hydraulic output. Servo valves like this are considered the “heart” of many high-performance machines because they provide continuous closed-loop control of hydraulic actuators.

Typical systems include:

• Turbine control
• Flight simulation / aerospace test rigs
• Injection molding machines
• Metal forming and press equipment
• Industrial robotics and heavy machinery

Key Features

• High-precision electro-hydraulic control
• Fast dynamic response and excellent repeatability
• Low hysteresis and high resolution
• Rugged, long-life construction for harsh environments
• Designed for closed-loop motion control systems
• Compatible with analog control signals

Moog servo valves are known for high dynamics, reliability, and long service life across demanding industries.
