Hydraulic Danfoss PVG 120 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.
General Characteristics :
- Load independent flow control :
- Oil flow to an individual function is independent of the load of this function.
- Oil flow to one function is independent of the load pressure of other functions.
- Good regulation characteristics.
- Energy saving.
- Up to eight basic modules per valve group.
