Data Sheet
Load Independent Proportional Valve
PVG 20
PVG 20 is a load independent proportional valve with
a flow up to 65 l/min and a pressure up to 240 bar.
PVG 20 is building on the modular, flexible and
proven Danfoss load independent proportional valve
concept.
The PVG 20 is designed especially to accommodate
the requirements of the Agricultural segment.
In addition, the PVG 20 valve program includes a
special summation valve, making proportional
summation of 2 pump flows into the same valve
group – decreasing cost and increasing energy
efficiency.
Features
•
Zero leakage work ports.
•
No pressure build- up on work port in
neutral.
•
No drop before lift.
•
Standard 4/3 and 4/4 spools.
•
Pilot pressure reduction valve with low
oil consumption.
•
Possibility of changing between double
and single acting work mode.
•
Proportional “intelligent” dual pump
flow summation.
•
CAN controlled (J1939/ISOBUS).
•
Single acting hitch module.
•
Pre compensated valve.
•
Possibility of mixing Pre and Post
compensated modules in the same
valve group, giving priority to the precompensated valves.
•
Thermal relief valves on work ports.
•
Various inlet types, OC, CC, HPCO.
•
Forced opening of pilot operated check
valves in float position.
