Description

The MOOG D136-002-005 D1 38-002-002 is a high-performance electrohydraulic servo actuator assembly, representing a complete motion solution from Moog’s precision engineering portfolio. This integrated package combines the D136-002-005 servo actuator with the D1 38-002-002 Linear Variable Differential Transformer (LVDT), forming a closed-loop system designed for exceptional accuracy and reliability in demanding industrial applications. The assembly functions as a high-force, precision positioning device, converting an electrical command signal (typically ±10 VDC) from a servo controller into a precise mechanical stroke. The integrated D1 38-002-002 LVDT provides continuous, real-time feedback on the actuator’s position, enabling the external control system to compare the actual position with the commanded position and make instantaneous corrections, ensuring pinpoint accuracy and repeatability.

This integrated solution is engineered for mission-critical applications where the integrity of the feedback loop is paramount. The value of the MOOG D136-002-005 D1 38-002-002 package lies in its guaranteed compatibility and optimized performance. By providing a matched and tested actuator-and-feedback pair, Moog eliminates the integration guesswork, ensuring optimal dynamic response, minimal hysteresis, and superior metering characteristics right out of the box. This robust assembly is built to withstand the harsh conditions of industrial environments, including high operating pressures, temperature variations, and significant side loads, making it the preferred choice for applications where performance cannot be compromised.

Technical Specifications

Main Features and Advantages

Integrated Closed-Loop Design: The foremost advantage of the MOOG D136-002-005 D1 38-002-002 is its factory-integrated closed-loop system. The D1 38-002-002 LVDT is specifically matched and calibrated to the D136-002-005 actuator, providing an exceptionally accurate and reliable feedback signal that is immune to the electrical noise common in industrial environments. This integration ensures perfect harmony between the actuator’s movement and the position signal received by the controller, resulting in unparalleled control stability, minimal deadband, and ultra-precise positioning. This eliminates the performance variances and commissioning delays that can occur when sourcing an actuator and feedback device separately.

Exceptional Durability and Performance: This assembly is built to Moog’s aerospace-grade standards, ensuring reliable operation in the most demanding conditions. The actuator body is constructed from high-strength steel with a hard-chrome plated piston rod that resists wear and corrosion. Aerospace-quality seals ensure leak-free operation over long service intervals, even under continuous cycling at full rated pressure. The integrated LVDT is housed within the actuator, protecting it from physical damage and environmental contaminants. The MOOG D136-002-005 D1 38-002-002 is designed to deliver consistent, high-force precision with minimal maintenance, maximizing system uptime and reducing the total cost of ownership.

Simplified Installation and Commissioning: By providing a pre-assembled and tested unit, the MOOG D136-002-005 D1 38-002-002 drastically simplifies system integration. Engineers and technicians are spared the complexity of mechanically mounting and aligning a separate feedback sensor, wiring it correctly, and tuning the control loop for optimal performance. The package includes all necessary internal wiring between the servovalve and the LVDT, reducing external connections and potential points of failure. This plug-and-play philosophy significantly reduces engineering time, installation errors, and commissioning time, allowing complex machinery to become operational faster and more reliably.

Application Field

The MOOG D136-002-005 D1 38-002-002 is deployed in high-performance industrial applications where its combination of high force and closed-loop precision is critical. A primary application is in material and component testing systems, where it is used in structural test frames and fatigue testers to apply precise, programmable loads for validating the integrity of airframe components, automotive suspensions, and building materials.

In metal forming and processing, this assembly provides precise control of rollers in steel and aluminum mills, ensuring exact material thickness and finish quality. It is also integral to the operation of high-performance simulation equipment, such as flight simulators and earthquake tables, where it must accurately replicate real-world forces and motions. In the energy sector, the MOOG D136-002-005 D1 38-002-002 is used for critical control functions in valve actuation for hydroelectric dams, steam turbine control, and in throttle systems for large gas turbines, where reliability and precision are non-negotiable for safety and efficiency.
