- 2 spool positions (hydraulic end position): only symbols C, D, K, Z, Y
- External pilot oil supply X or pilot oil return Y:
- Observe the maximum pilot pressure according to Technical data!
- Internal pilot oil supply (version “ET” and “E”):
- Observe the minimum pilot pressure according to the Technical data!
- In order to prevent inadmissibly high pressure peaks, a throttle insert “B10” has to be provided in port P of the pilot control valve (see Product description).
- You must moreover provide the pressure reducing valve “D3”.
- Only in connection with throttle insert “B10”
Notice: The manual override cannot be allocated a safety function and may only be used up to a tank pressure of 50 bar.
