Warning
PVEA is not for use on PVG 100.

Variant of hydraulic subsystem: PVHC

The PVHC does not work as a PVE and does not have transducer, anti cavitation nor protection against
tank pressure spikes. It is necessary to use the PVHC in combination with 25 bar [362.6 psi] pilot pressure,
and standard FC spools fitted for hydraulic actuation. Because of the 25 bar pilot pressure, it is not
possible to combine PVHC with PVE on a PVG.
Hydraulic subsystem variant: PVHC
With electrical proportional actuation, the main spool position is adjusted so that its position corresponds
to an electrical control signal. The control signal is converted into a hydraulic pressure signal that moves
the main spool in the PVG. This is done by means of two proportional pressure-reducing valves. The
electrical actuator can be controlled either by a current amplifier card, or directly from a programmable
micro-controller.
