Mechanical subsystem
The mechanical subsystem gives interface to valve and control system and provides protection to
hydraulic and electrical/electronic subsystem. The LVDT, not used on all variants, gives feed back to
electronics on spool position. The LVDT is calibrated in production and recalibration should only be done
in special cases. The standard PVE has an aluminum block for distributing pilot oil. PVE with anodized
block are available.
The connector gives the electrical interface to power and control system. Danfoss have a variety of
connectors. We know that tradition and the aspects of serviceability are important when our customers
choose. We have chosen the Deutsch connector as our main solution. The quality of wiring has direct
influence on water integrity and signal quality therefore disturbance or changes in cabling can influence
safety and performance.
PVE connectors: Hirschmann/DIN, AMP and Deutsch
Electronic subsystem
The PVE (A/ H/ M/ S/ U) control signal is a low current voltage, a PWM can also be used. The PVEP has
build-in a PWM evaluation and cannot be controlled by proportional voltage. The control signal is
referred to as U
S
.
