Moog D061-613C

The Moog D061-613C is a direct drive valve manufactured by Moog. This advanced electrohydraulic valve uses Moog's direct drive motor technology to achieve servo-quality performance with exceptional contamination tolerance and long service life.

Overview

The Moog D061-613C direct drive valve represents the latest evolution in electrohydraulic control technology. Unlike traditional servo valves that use a torque motor and nozzle-flapper pilot stage, direct drive valves use a linear force motor to position the main spool directly. This eliminates the pilot stage entirely, removing the primary source of contamination sensitivity in conventional servo valves.

The result is a valve that delivers servo-grade dynamic response, accuracy, and repeatability while operating reliably in hydraulic systems with standard industrial filtration levels. The D061-613C achieves fast step response, low hysteresis, and excellent frequency response characteristics comparable to traditional two-stage servo valves, but with dramatically reduced maintenance requirements.

Integrated position feedback (LVDT) on the main spool provides accurate closed-loop spool position control, ensuring consistent performance over the full operating life of the valve.

Key Features

• Direct drive motor technology — no pilot stage, no nozzle-flapper
• Servo-quality performance with industrial contamination tolerance
• Fast dynamic response comparable to two-stage servo valves
• Integrated LVDT spool position feedback
• Dramatically reduced maintenance compared to traditional servo valves
• Long service life with consistent performance characteristics

Applications

Moog direct drive valves like the D061-613C are ideal for hydraulic presses, injection moulding machines, metal forming equipment, industrial test rigs, power generation systems, and any application where servo performance is needed but the maintenance burden of traditional servo valves is unacceptable.
