MOOG D136-003-001

Description

Technical Specifications:

• Product Model: D136-003-001 / MSC-R-D136-003-001

• Manufacturer: MOOG Inc.

• Product Category: Two-Stage Electro-Hydraulic Servo Valve / Multi-Axis Servo Real-Time Control Module

• Control Cycle: 250 μs – 1 ms (configurable)

• Supply Voltage: 24 VDC

• Valve Type: Two-stage (Torque Motor + Flapper/Nozzle + Spool)

• Input Signal: Low-current electrical signal (e.g., ±10 mA)

• Axes Managed: Up to 8 servo axes (configuration dependent)

Functional Features:

• Two-stage operating principle: first stage (torque motor and flapper/nozzle) converts electrical signal to differential pressure; second stage (spool valve) directs hydraulic fluid to actuator

• High precision and resolution for extremely fine fluid flow control

• Fast dynamic response for high-frequency operation

• External null shift adjustment mechanism for mechanical bias and null drift correction

• Robust construction for harsh operating conditions

• Integral micron-rated inlet filter for contamination protection

• Military-grade design standards

• Deterministic performance with sub-millisecond loop times and nanosecond-level jitter

• Built-in multi-channel analog inputs (LVDT, strain gauges), digital I/O, and encoder interfaces

Performance Parameters:

• Control Cycle: 250 μs – 1 ms (configurable)

• Maximum Axes: Up to 8 servo axes

• Supply Voltage: 24 VDC

Material Composition:
Military-grade components with full metal shielded enclosure. Wide-temperature components rated for continuous operation in extreme environments.

Structural Features:
The valve features a two-stage architecture with a first-stage torque motor and flapper/nozzle assembly, and a second-stage four-way sliding spool. The module installs in the D136 chassis main control slot and connects to I/O modules via high-speed parallel backplane bus. All critical signals employ differential transmission and opto-isolation.

Working Principle:
A low-current electrical signal (e.g., ±10 mA) applied to the torque motor coils creates a magnetic force that deflects a flexure tube and connected flapper positioned between two nozzles. This deflection creates a differential pressure that acts on the ends of a four-way sliding spool. The spool shifts to precisely direct hydraulic fluid to and from a single or double-acting hydraulic actuator. The valve incorporates electrical feedback for closed-loop control.

Advantages and Strengths:

• Extreme synchronization with microsecond-level response

• FPGA and hardware timer协同 processing for deterministic control

• High integration reduces external signal conditioning requirements

• Military-grade robustness with EMI immunity and vibration tolerance

• Open architecture with standardized API and communication protocols (UDP/TCP over Ethernet)

• Supports MATLAB/Simulink real-time simulation environments

• Supports Model-in-the-Loop (MIL) and Hardware-in-the-Loop (HIL) testing

Applicable Industries:

• Aerospace flight simulators and motion platforms

• Six-degree-of-freedom (6-DOF) vibration tables

• Structural loading test systems

• Energy equipment test platforms

• Material testing machines (tensile, fatigue)

• Automotive NVH testing centers

• Wind turbine blade fatigue test rigs

Model Series:
MOOG D136 Series Motion Control System

Installation Requirements:

• Install in D136 chassis main control slot

• Connect via high-speed parallel backplane bus to I/O modules

• Connect to power amplifiers or electro-hydraulic servo valves through D136 backplane
