Hydraulic Servo Valve MO-OG Series G761-3033B G761-3034B G761-3002B G761-3003B G761-3004B Hydraulic Solenoid Valve

The G761/761 Series flow control servovalves are throttlevalves for 3 and preferably 4-way applications. They area high performance,2-stage design that covers the rangeofrated flows from 4 to 63 l/min (l to 16.5 gpm) at 35 ba(500 psi) valve pressure drop per spool land.
The output stage is a closed center, four.way slidingspool, The pilot stage is a symmetrical double-nozzleand flapper, driven by a double air gap, dry torque motor.Mechanical feedback of spool position is provided by acantilever spring, The valve design is simple and rugged fordependable, long life operation
The design is simple and rugged for dependable, long lifeoperation. The output stage is a closed center, 4 way
sliding spool. The pilot stage is comprised of a symmetrical,double nozzle dry torque motor. The Znd stage spool
position is controlled by a carbide tipped feedback wire.The carbide ball on the end of the feedback wire is a
mandatory design requirement that ensures high accuracy,reliable operation and long service life. All of our servovalves are known for high accuracy and reliable operationeven in the harshest industrial applications.
These valves are suitable for electrohydraulic position,speed,pressure or force control systems with high dynamic
response requirements.
