PVE characteristic - control by voltage
2.5V 5V
The PVE variants PVEA/H/M/S/U/P and the PVED-CC/-CX has a closed loop control supported by a spool
position sensor that ensures integrity towards flow forces and oil viscosity.

* Hysteresis (control signal/spool travel) is indicated at rated voltage and f = 0.02 Hz. (one cycle = neutral
→ full A → full B → neutral)
The standard PVE's are proportional activated actuator except PVEO which is on/off. The PVE's have fault-
monitoring.
•
PVEU is available with PVEH and PVES hysteresis
•
PVEP, PVED-CC and PVED-CX are available with PVES hysteresis
The values are typical test data for exact ranges, see PVE Technical Information, 520L0553.
