MOOG Servo Valve G772K240A Application Scenario

MOOG Servo Valve G772K240A is a high performance two-stage electro-hydraulic flow control servo valve manufactured by MOOG. Its core features are high frequency response, high accuracy, high flow and rugged design, making it ideal for demanding industrial applications.

The following are some typical applications of the G772K240A servo valve:

Metallurgical equipment (metal rolling):

Rolling mill hydraulic screw-down system (Hydraulic AGC - Automatic Gauge Control): this is one of the most important application fields. It is used to precisely and quickly control the roll position or rolling force, so as to realize the high-precision control of the thickness of the strip (steel plate, aluminum plate, copper strip, etc.). Its high frequency response capability is essential to ensure uniform strip head and tail thickness and fast response to load changes.

Plate shape control system: it is used to control actuators such as bending roll and displacement roll, adjust the convexity or contour of roll, and improve the flatness of plate and strip.

Tension control system: accurately control the strip tension in the coiler, uncoiler and other equipment.

Material testing machine:

Electro-hydraulic servo fatigue testing machine: used for high-frequency and high-precision dynamic load (tension, compression, bending and torsion) simulation of metal, composite material, rubber, plastic and other samples. G772K240A's high flow and high frequency response capabilities enable it to accurately reproduce complex load spectra and meet stringent test standards (e.g., auto parts, aerospace structural parts testing).

Structural test bench: simulate the response of buildings, bridges, large mechanical structures, etc. under real or extreme load.

Energy and electricity:

Turbine speed governing system: it is used to control the HP fire-resistant oil system, accurately adjust the opening of the main throttle valve or control valve of the turbine, and realize the power and speed control of the generator set. It requires fast response, high control accuracy and high reliability.

Turbine governor system: similar to turbine, controlling the opening of wicket gates or needles.

Valve test bench: used to test the opening and closing characteristics and sealing performance of large valves (such as nuclear power valves), requiring high-precision force or position control.

Ship and Marine Engineering:

Steering engine system: It is used for the hydraulic system of the steering engine of large ships or high-performance ships, providing fast and accurate rudder angle control.

Dynamic positioning propeller control system: control the propeller angle or pitch to realize the accurate positioning of the ship.

Platform/ship motion simulator: simulate wave motion for test equipment or training.

Industrial machinery and automation:

Large injection molding machine: it is used to control injection, pressure maintaining, mould closing and other actions, especially for occasions with high requirements for speed and pressure control accuracy.

High-end machine tools: for example, precise position/force control of spindle drive or feed system of large planer-milling machine and grinding machine (the application is less than the previous ones, but it can also be selected when the accuracy requirement is very high).

Heavy-duty robot joint drive: application requiring large driving force and high dynamic performance.

Paper machine: such as key positions for controlling the lip opening of headbox and roller gap of calender.

Other areas requiring high performance hydraulic control:

Large vibration table: simulate earthquake or other vibration environment.

Wind tunnel equipment: control nozzle or model attitude.

Special vehicles: active suspension systems for military vehicles or large engineering vehicles.

Summarize the application characteristics of G772K240A:

High dynamic response: it can quickly and accurately follow the changed input signal (fast step response and high frequency response).

Large flow capacity: capable of driving actuators (oil cylinder and motor) requiring large hydraulic power.

High-precision control: provide accurate flow or pressure output to realize high-precision position, speed, force or pressure control.

High reliability: The MUGG Servo Valve is known for its sturdiness, durability and reliability and is suitable for continuous operation in industrial environments.

Complex control: it is commonly used to realize closed-loop feedback control and solve complex control problems such as load change and disturbance.

In simple terms, MOOG G772K240A servo valve is a "sharp tool" to solve the high-speed, powerful and high-precision dynamic control tasks required by the hydraulic system. It plays a key role in the core industrial fields such as metallurgical rolling, high-end material testing, speed regulation of large energy equipment, etc. When selecting, ensure that the flow, pressure rating and dynamic performance meet the specific application requirements, and the cleanliness of the hydraulic system must meet the strict requirements of the servo valve.
