The 760 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 1 to 15 gpm at  1000 psi valve drop.The   output stage is a closed center,  four-way, sliding spool.The pilot  stage is a symmetrical doublenozzle and flapper, driven by a  double air gap, dry torque  motor. Mechanical feedback of  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  electrohydraulic position,  speed, pressure or force control systems with high dynamic  response requirements.  

Principle of operation  

An electrical command signal  （flow rate set point） 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.

Movement of the spool opens  the supply pressure port （P） to  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 on  the armature/flapper assembly

Once the restoring torque  becomes equal to the torque  from the magnetic forces, the  armature/flapper assembly  moves back to the neutral  position, and the spool is held  open in a state of equilibrium  until the command signal  changes to a new level.

In summary, the spool position  is proportional to the input  current and, with constant  pressure drop across the valve,  flow to the load is proportional  to the spool position.
