PVEH, proportional high
PVEH adjusts the main spool position so that it corresponds to an electrical control signal – for example
from a remote control unit.
The control signal (set-point signal) is converted into a hydraulic pressure which moves the main spool.
The position of the main spool is converted in the positional transducer (C) to an electric signal (feed-
back signal). This signal is registered by the electronics.
The variation between the set-point signal and feed-back signal actuates the solenoid valves, thus the
hydraulic pressure moves the main spool into the correct position.
