(measured with HLP46, ϑOil = 40 ±5 °C)
Notice:
The specified performance limits are valid for use with two directions of flow (e. g. from P to A and simultaneous return flow from B to T).
Due to the flow forces acting within the valves, the admissible performance limit may be considerably lower with only one direction of flow (e. g. from P to A while port B is blocked)!
In such use cases, please consult us!
The performance limit was determined when the solenoids were at operating temperature, at 10 % undervoltage and without tank preloading.
