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”

pSt	Pilot pressure
ppilot min	Pilot pressure, minimum
ptank	Tank pressure
pö	Cracking pressure

Preferred types and standard units are contained in the EPS (standard price list).
