FLOW CONTROL SERVOVALVES J869 SERIES - 2

J869 Series flow control servovalves are throttle valves for 3 and preferably 4 way applications. They are a high ‐ ‐ performance, two-stage design that covers the range of rated flows from 3.2 to 64 Lmin at 7.0 MPa valve drop. The output stage is a closed center, four-way, sliding spool. The pilot stage is a symmetrical double-nozzle and flapper, driven by a double air gap, dry torque motor. Mechanical feedback of the spool position is provided by a cantilever spring. The valve design is simple and rugged for dependable, long life operation. These valves are suitable for Industrial Robots,...

FLOW CONTROL SERVOVALVES J869 SERIES - 3

An electrical command signal is applied to the torque motor coils and creates a magnetic force, which acts on the ends of the pilot stage armature. This causes a deflection of armature flapper assembly within the flexure tube. Deflection of the flapper restricts fluid flow through one nozzle, which is carried through to one spool end, displacing the spool. to Movement of the spool opens the supply pressure port P one control port while simultaneously opening the tank port T to the other control port. The spool motion also applies a force to the cantilever spring, creating a restoring torque...

ELECTRICAL CONNECTIONS, ORDERING INFORMATION, SPARE PARTS AND ACCESSORIES Electrical Connections Rated current and coil resistance A variety of coils are available for J869 Series Servovalves. Coil connections A four-pin electrical box connector that mates with an MS31 06A‐ ‐ cable connector standard. All four torque motor 14S 2S is leads are available at the connector so external connection can be made for series, parallel or single coil operation. The servoamplifier responds to input current, so a servoamplifier that has high internal impedance as obtained with current feedshould be used....
