Explanation


EMG Servo Valve Type SV2-16

A pilot valve SV1-10, which is suitable for pressure control, is placed on a valve block. Together with the main valve, which contains a piston slide valve, an inductive position transducer as well as a control amplifier, a closed control system is realized. Via the internal lines of the pilot valve the piston slide valve is pushed with pressure against the spring force. By this the hydraulic fluid is led to the operating lines A or B. The inductive position transducer meanwhile monitors the position of the main control piston. The volume flow is determined by the position of the piston slide valve and is proportional to the input current of the control amplifier. The piston is held in the middle position by two pressure springs, e. g. in case of power breakdown.

Technical features

  • temperature- and pressure-independent zero point stability
  • practically constant dynamics (almost independent of pressure and drive)
  • large control distances, long service life, low leakage flow
  • mechanical manual/emergency control and external performance monitoring
  • spring-centred rotary slide (zero position in the event of an electrical power failure)
  • standard connections, standard plug

Customer benefits

  • cleaning flush of the valve during operation
  • also suitable for low pressure levels
  • single- and double-stage construction possible (SV1-.../SV2-...)
  • guaranteed minimum friction losses
  • high repetition accuracy
  • huge range of performance for single- and double-stage valves
  • high level of reliability
  • extremely easy to service
