Diagrams/characteristic curves
(measured with HLP46, ϑOil = 40 ±5 °C)
Reduced pressure at port P① dependent on the command value (manufacturing tolerance)
| 1) | In order to be able to adjust several valves to the same characteristic curve, the manufacturing tolerance can - with version "Z3DRE" - be changed at the external amplifier (see "Accessories") using the command value attenuator "G". In this connection, do not set the pressure higher than the maximum set pressure of the pressure rating with command value 100%. |
