Moog G631-3005B

The Moog G631-3005B is a flow control servo valve manufactured by Moog. This precision valve provides accurate, proportional control of hydraulic flow rate for demanding industrial and aerospace flow regulation applications.

Overview

The Moog G631-3005B flow control servo valve is specifically designed for applications requiring precise regulation of hydraulic flow independent of load pressure variations. This valve incorporates Moog's proven servo valve technology with pressure-compensated flow control functionality, ensuring consistent flow delivery regardless of downstream load changes.

Flow control servo valves in this series use Moog's torque motor pilot stage with a precision metering spool, providing excellent flow linearity and fast response to command signal changes. The pressure compensation mechanism maintains stable flow output even under varying system conditions, making these valves ideal for applications where consistent actuator speed is critical.

The G631-3005B is designed for integration into closed-loop flow control systems and is compatible with standard Moog servo amplifiers and flow feedback transducers. The valve mounts on standard hydraulic manifolds and follows Moog's industry-standard interface specifications.
