PVE Electro-hydraulic Actuation

The analog PVE Series 6 is an electro-hydraulic actuator used to control a single work section of a PVG
proportional valve group. The PVE actuator program for PVG 16 includes variants with different
performance levels and features.
The actuator positions the main spool in a PVG work section to control either the flow or the pressure of
the oil distributed to and from the work function. The control signal to the actuator is an analog voltage
signal, enabling the user to operate the work function remotely by means of a joystick, a controller or the
similar.
The electro-hydraulic solenoid valve bridge of the actuator is available in different designs utilizing
different regulation principles, depending on performance variant. The actuator positions the main spool
by distributing pilot oil pressure to either side of it, pressurizing one side by pilot pressure while relieving
the opposite side to tank and vice versa. All proportional actuators feature a closed- loop spool control
and continuous fault monitoring.
The analog PVE Series 6 actuator program for PVG 16 features two different main hydraulic principle
variants (PVEO and PVEA).
The different hydraulic principles combined with the different solenoid valve regulation principles
determine whether the actuator controls the spool proportionally according to a demand signal or
ON/OFF according to a voltage signal. The voltage control characteristic of the PVE actuators is shown in
the figure below on the left side.
