The 30 Series is a two-stage, ow control, double-nozzle, mechanical feedback
servo valve that has a stainless steel body and integrated torque motor in an
environmentally sealed compartment. Its nozzle-apper design is a proven
technology for applications where high response, stability and accuracy are
required in a compact package.
The 30 Series Servo Valve is designed to provide a long service life even in
demanding and extreme conditions. These products perform reliably in high and
low temperatures, and high acceleration, shock and vibration environments.
Along with the 24 Series Servo Valves, this product is part of our proven
micro hydraulics offering that is well known for high power to weight ratio and
efciency, while delivering high dynamics and precise force control for better
overall system control.
WHAT MOVES YOUR WORLD

INSTALLATION DRAWING
COIL RESISTANCE
The effects of coil resistance changes can be essentially eliminated
through the use of a current feedback servoamplier having a high
output resistance such as the Moog G123-825 Buffer Amplier.

TECHNICAL HYDRAULIC DATA
Note:
1. Resistance values at 20°C (68°F) 10 % tolerance
2. Inductance values are typical to 50 Hz, servovalve pressurized. Inductance is not normally measured on individual servo valves.
*Inductance values per coil with differential operation (class A push-pull).
Seal Material: FKM
System Filtration: High Pressure lter (without bypass but with dirt
alarm) mounted in the main ow and if possible directly upstream of
the valve
Class of Cleanliness: The cleanliness of the hydraulic uid greatly
affects the performance (e.g., spool positioning, high resolution) and
wear (e.g., metering edges, pressure gain, leakage) of the servo valves
Recommended Cleanliness Class
For functional safety ISO 4406 <17/14/11
For longer service life ISO 4406 <16/13/10
Filter Rating recommended
For normal operation b

≥ 75 (10 µm absolute)
For longer life b

ORDERING INFORMATION
Moog Global Support is our promise to help you maximize uptime and get more from your machine
investment. Moog has the expertise you can trust to perform the highest quality repairs to ensure like
new performance for your servovalves. Only Moog technicians use authentic Moog OEM replacement
parts to ensure “like-new” performance after every repair. Moog products are repaired to the original
specications and returned to you with a renewed warranty. Moog standard repair levels are available
for this product and Moog offers options for express service in many of our locations.
Moog provides a wide variety of accessories that our customers may need for hydraulic valves. The
Moog G123-825 Buffer Amplier is a DIN Rail mount module that solves the common problem of the
input signal being incompatible with the valve drive requirements. For more info visit www.moog.com
or contact your local ofce.
