MOOG G771K625A Servo Valve Overview

Manufacturer: Moog
Model: G771K625A
Type: Electro-hydraulic servo valve (G771 Series)

Product Description

The MOOG G771K625A is a high-performance electro-hydraulic servo valve designed for precise flow and motion control in industrial and automation systems. It belongs to Moog’s 771/772/773 direct-operated servo valve family, widely used in demanding hydraulic control applications.

This model replaces the earlier G771K625 and provides analog signal-controlled flow regulation for high-precision systems.

Key Features

• Electro-hydraulic servo valve for analog signal control
• Direct-operated flow control design
• Compact and rugged construction for long-life operation
• High dynamic response and accuracy
• Suitable for harsh industrial environments
• Compatible with PLC/DCS hydraulic control systems
