PV - Proportional Voltage Valve:
Namely, Danfoss PVG32, pilot operated proportional valves with "on-board" electronics,
spool position and fault monitoring.

The PV valve signal is a low power ratiometric voltage signal that references the switched
power output (machine voltage).
I.e. 50% of machine voltage = No flow
25% of machine voltage = Full lower
75% of machine voltage = Full raise
Danfoss diagnostics: Green LED on valve = OK
Red LED on valve = Fault
Application Notes: PV valves provide larger flows up to 32 GPM (120 l/m) and have
more accurate flows. For best performance use PVEH actuation modules and linear
spools.
Valves are easily converted to interface with open center, closed center, and load sensing
hydraulic systems.
Raise cylinder port is the port closest to the black electronics module.
