19 Information in the plain text *
  1. External pilot oil supply X or return Y:
    • with NG10, version SO30 has to be used if sandwich plates are installed. The identification SO30 has to be used at the end of the type designation (sandwich plate).
    • the maximum admissible operating parameters of the pilot control valve must be observed!
    • observe the maximum pilot pressure!
  2. Internal pilot oil supply (version “ET” and “E”):
    • minimum pilot pressure: please observe the Technical data!
    • to prevent inadmissibly high pressure peaks, a “B10” throttle insert must be provided in port P of the pilot control valve (see Pilot oil supply).
  3. 2 spool positions (hydraulic end position): only piston C, D, Y, K ,Z
  4. only in connection with throttle insert “B10”
