Valve System
Load sensing proportional valve type PVG 120 is a combined directional and flow control valve which is
supplied as a valve group consisting of modules specified to match particular customer needs. The
flexible nature of this valve will allow an existing valve bank to be easily adapted to suit changes in
requirements.

‒
Oil flow to one function is independent of the load pressure of other functions
•
Good regulation characteristics
•
Central pilot supply built in when the valves are actuated electrohydraulically
•
Energy-saving
•
Up to eight basic modules per valve group
Pump Side Module – PVP
•
Built-in pressure relief valve
•
System pressure up to 400 bar [5800 psi]
•
Pressure gauge connection
•
Versions:
‒
Open centre version for systems with fixed displacement pumps
‒
Open centre version prepared for an extra relief module
‒
Closed centre version for systems with variable displacement pumps
